I guess my approach with people is a little extreme, because I expect people to be very sensitive and considerate, and at any mistake, I drop them. I did it more than once before. I once actually unfriended someone whom I can call my only friend on Facebook because he did something I perceived as inconsiderate (I befriended him later, though). Obviously, this isn't working for me. I don't want to be around insensitive or inconsiderate or self-absorbed people (I'd rather be alone), but I guess allowing some room for occasional mistakes is more realistic.
