I'm going to describe what I feel like when I'm around the following two groups of people. I want you to guess which two groups these are.
I feel relatively comfortable talking to these people. Conversation flows easily, and we can generally talk about anything and everything that comes to mind. When something is bothering me, they generally notice, and help me feel better about it. In return, I generally notice when something is wrong with them, and they appreciate my concern. If they happen to say something that I take personally, and then I get angry, say something spiteful, then turn around and apologize, they'll quickly forgive me and continue the conversation. Many of them are intelligent enough to understand the things I talk about, but even the ones that aren't as intelligent generally know what I need to hear, and can often tell exactly what I'm worried about. Many of them admit to having worried about the same things. They generally don't make me nervous or uncomfortable in the least, and often help me feel relaxed and at ease, especially if I know them well.
Most of these people make me feel a bit nervous and intimidated. I can usually talk about very basic things, but I'm so nervous that I don't sound as intelligent as normal. Also, they often accuse me of talking too much, or talking too fast, as if they were computers with very poor voice recognition software. If I try to discuss anything much deeper than the superficial, they seem to be repulsed. If they do anything that offends me, and I show signs of it, they get weirded out, and either threaten me, or go away from me in disgust. Most of the time if I'm discussing something, they get confused if I don't explictly and pedantically explain every step of where I'm going with something, and can't seem to pick up on the "flow." By the time I'm halfway through, they're bored. Some of them are more intelligent, but I have to careful only to discuss neutral topics with them, such as computing, because otherwise they'll feel nervous. A very few of them actually are perfectly nice, and my discomfort lessens the longer I know them, but there's always something about them that makes me a little tense.
What do you think these two groups are?
