Kissing.

really, I wonder this all the time when I'm kissing someone.
Who decided the action of kissing would be an act of affection?
I know we're animals or whatever, and it probably derives from that, but still...

I wonder like, who invented the kiss...
it's just weird when I think about how SO many years go by, and kissing is still a means of showing someone how you feel. I think I should research this...and maybe other affectionate actions that may have died out.
