Well it's obviously different for everyone. But for me it would just be spending time with them really. If I like someone and consider them special, then it shouldn't have to be shown anyway. In the extremely instance that I even met such a person then webwould both just know. I don't like expressing my feelings, having any expectations placed on me (especially emotional) and too much displays of affection, etc. Those types of things make me feel annoyed and suffocated.

So the answer is I don't like to show someone I care really. But they should just know by how well we get along and seem to understand each other or whatever. That doesn't mean I won't ever do or say little things for them but if I did then I wouldn't want it to have any meaning, it would just be because I want to, it doesn't mean I care. I may 'care' but to me it shouldn't have to be shown if that makes sense. And I could really resent it if someone expected to show I care if I got that sense from them. It's not about that. At least for me anyway.

And I really don't like being around people in general so just taking any active interest in someone is pretty rare and a big deal for me. Also "my presence is a present". That should be more than all they need and they should appreciate it.
