About Love

Some of my friends fallen love with someone even if they do not know he/she and they has never spoken to he/she.
That phenomenon looks so mysterious to me.
I usually fell love with a person I had a good conversation and that experience makes me feel that I want to talk that person again.
Conversation is like tennis. I simply love a guy who returns a boll in an interesting way and make me laugh. If he also happy to talk with me, I am more than happy.
Of course I like beautiful boys.
But as long as the person I like is not stinky or something, I am happy with him because I like him.
Have you ever fallen love with someone with their appearance?
