Oh well, I don't deal with it so well, but I guess not so bad either.
Expectations and dissapointment... Such dangerous parts of social interaction, aren't they? I think we, as INTPs, don't expect that much in a way, for example, we usually don't expect someone to do something good for us, as other people do. But I think we create expectations in some other ways. I don't know, though, it might be just me... I just find my stupid teenager hormones too difficult to deal with. And rather amusing to play with my own mind and analyzing why I act the way I do.
What about friends? Are they just acquaintances, or real friends? Considering a real friend as someone who you can talk with about anything. Or in the middle? I'm a little interested about how you live in real life.
