>>1 Some people can't get close to people very easily, but that means that it becomes so much more significant and special when you find someone who you can.
Although, I don't really get the anger part of this because if you get angry are you really someone who feels nothing? Or do you feel nothing for other people? And that's part of why you're angry?
One way of looking at this is that you don't feel like you should have to like someone, like it's something expected of you, because sometimes it loses it's meaning that way. I wouldn't blame you or judge you for not feeling anything for others.
And besides, if you feel guilty then it just proves how good your intentions are.
