I sometimes ask a girl to mind my things in the library, or suggestions on a place to eat etc. I don't do this to hit on them, just being social.

During a handshake while we continue to talk I sometimes put my other hand onto hers as well and it produces some strange reactions. They seem a lot more friendly, want to talk to me longer, push their hair around, or get nervous. It's a fun trick i've been doing just to see what it does to people.

What do you guys think of this, and how does it normally effect girls in your experience?
