The thing about greeting people

It's easy for me to feel awkward. I don't know, maybe I have asperger's or something. Really, though, some greetings aren't exactly my favorites. For example...

Hand-shaking
-It feels kind of forced, if you ask me. Plus, it's not the most comfortable gesture; well, to me, anyway. My hands are always cold; I feel like every time I shake someone's hand I have to apologize.
Peck
-I don't get why adults give each other a peck on the cheek. Eh, I wish I had more to say on this. Bottom line, I don't understand it.
Saying "good-bye"
-I hardly ever say good-bye. I usually say, "See ya later." Good-bye makes me feel like I'll never see that person again. Like most people, I hate saying good-bye. I'll say just "bye" every now and then, but "good-bye" seems too...final, you know?

However, some greetings are great:

Hugs
-I LOVE HUGS. End of story.
Hand shakes
-Yes, they seem (I don't want to say gay) childish, but that'd be quite fun to be involved in a 'secret handshake' between a friend and myself. Friendship bracelets, however, is where I draw the line; I'm too grown-up for that, sorry.
High-fives
-They're just awesome. I feel energized after one. It's funny when you miss, but a friend of mine told me that, if you just look at the other person's elbow, you'll never miss.
