I can only speak for myself, but...
What do you do to get an ENTP to REALLY like you? I don't necessarily mean romantically, but just really like you in general.
Simple: keep me guessing. If I find you unpredictable, that's worth its weight in gold. I don't mean in the sense of flaky, neurotic, crazy etc, but I just mean that you react to things I say in ways I don't expect. Which is difficult, cos it means you've got to know what the parameters of what I expect actually encompass, which is quite a variety of things. But if you can even now and again do something that makes me laugh with appreciation at the sheer originality of it, you'll have won my heart, for one.
I can also turn this around and say, what do you (ENTPs) really like in people?
Directness, but not of the immature kind that thinks that it has a right to say anything just because it's "true" (in their opinion) - they need to recognise when "truth" isn't called for or solicited, and speaking it isn't constructive, just hurtful. Authenticity, a person who is what they are and doesn't try to be otherwise, I appreciate - be yourself and don't try to impress me. Energy and independence. Slipperiness... I know a guy who's like a sorta fairy/elf character, you know? Whatever I say, I try to pin him down, and he laughs and sidesteps everything, and makes me laugh with it, and he laughs at me though not in a cruel way, and it drives me crazy
What makes you feel/know that you can trust someone? What makes you want to keep someone in your life?
When, over a period of time, they've done everything they've said they'd do, stood by everything they've said and taken responsibility when it turned out to be wrong, they've shown that they're capable of saying, directly, when they have a problem with something and haven't done the martyr act at any point, and kept every bargain I've made with them. When they've shown an openness and generosity of spirit and been consistent and constant in their dealings with me, and made as much effort to keep in touch with me as I have with them (rather than leaving me to always take the initiative, as so many do).
People pretending to be something else to try to impress others. Snobbery, people thinking something about them makes them intrinsically better, morally or any other way, than someone else. Small-mindedness. Meanness both with material things and meanness of spirit. When somebody doesn't just trust that I'll do what I say I'll do, regardless of how many times I prove this to be the case, and they keep checking up on me, confirming, etc etc. Unwarranted pessimism - pouring cold water on plans, ideas, whatever.
What do you do when you're annoyed with someone/don't want to talk to them?
If it's a long-ish term thing, then first off, I tell them I'm annoyed and why. I use direct, clear and explicit, carefully chosen words that mean EXACTLY what they say on the tin. Though, I lace it with tact as much as I can without compromising truth and accuracy. If they're willing to talk about it, then I try to work with them to sort out the problem. If they react with hostility and defensiveness, and take it all personally, then I give up pretty quickly and just don't bother with them, and leave it up to them to come back when they're willing to reason. If that's never, so be it. I won't go creeping to them unless it can be clearly shown that I've done something that needs apologising for. Even then, if the person is still not willing to reason out about the problem between us, then whether they accept my apology or not, I still won't chase them up.
If you don't want to talk to someone, would you tell them? Ignore them?
Ordinarily I'd say tell them. Always. Even when I know I shouldn't, I usually can't help myself. I thirst for clarity and openness so much, I can't usually stand to have things hushed up, swept under the carpet or whatever. If I have a problem with someone they will usually know about it pretty quickly. The only time I can think of when I might not tell them would be if experience had told me there's no point, that they're not likely to listen/be willing to reason, or whatever. If that's the case though, it's not going to be somebody I consider a friend - it'll be someone I have little respect or liking for, but have no choice but to deal with such as a colleague/superior etc.
What do you do when you really like someone? (again, not necessarily romantically)
If not romantically, then I tell them, straight up, either directly or, to avoid gushing and awkwardness and big emotional scenes, I'll tell them through maybe jokey understatements, or just by showing obvious willing and desire to keep their company, initiating contact and all that.
If romantically... well. I don't tend to tell them, if I can help it, not unless I have a good reason to believe that the feeling's mutual. If I do, then I do tell them, yes, pretty directly.
Do you find yourself communicating with friends first, or wait for them to communicate with you?
The latter, as implied above... I do get very tired of always being seen as the energetic, get-up-and-go one, and people looking to me to suggest things, think of things, nobody trying to do it themselves, just relying on me to always be the driving force behind a social circle. Hence why, when I meet someone who has their own energy/impetus and won't just suck mine, they quickly become very high in my regard.
