1) My personal values hold that I don't lie. Some might, because they want to protect you or not hurt your feelings. Exaggeration is something you might consider to be the case. And objectively you're probably right, but some of us experience things intensely, enjoy telling a good story and have a sucky memory with an overactive imagination. It kinda..gets tangled up. It's not meant to be malicious, it's meant to entertain.
2) That's a matter of perspective. I do this all the time. I make sure people are aware of it though before I start, and that they know what the outcome will be. Took me a while to realize that othesr didn't work like that and that I had to build in those disclaimers to make sure I didn't hurt anyone. Also, it's not that I get tired with you, it's just that I only have a little bit of time and a lot of interesting people to meet. Each and everyone is different however and special in their own way. Some will be more dear to me than others, because I connect better with them. However, that does not mean that I don't also very much care for those that I don't have that connection with. Take it for what it is worth, I know this is a hard one to understand, from experience.
3) Yes, this is true. What's so wrong about that? I won't though, if they ask me to do something against my Fi. Other than that, why on earth would I refuse a request from someone. I have no good reason to do so. I appreciate people helping me, why wouldn't I do the same for them ,especially if it's just a small thing?? I used to be even more like this when I was younger, as I..I dunno, I found it offensive to refuse people things, especially if it was a small effort required. Why would I be mean to them? Nowadays, I take more distance, check who the person in front of me is, and check my own schedule. But I still am very willing to help them out.
4) Looking down isn't usually meant that way. It stems from the frustration that we cannot communicate our 'logic'. Fi is...hard to explain. It's also passionate, and very protective of what's important in our eyes. Since our memory sucks, we cannot tell you how many infinite patterns we went through and which ones they were, and how many associations we had to make to get to this result. All we know is that to us, this is true. And you hammering it as if it's a useless piece of junk, doesn't put us in a good mood. So expect to get hit back with a Te-hammer
Oh and...we're not rational creatures in the traditional sense of the word
Btw..neither are you, at least a part of you, or you wouldn't find yourself frustrated over being attracted to an irrational creature in the first place
