Just what is clified as flirting and do we always intend to do it?

Flirting is just your body language and how it changes when your with someone you like. For example, girls often play with their hair which can be a sign of flirting. What is clified as flirting is merly opinion but when your with someone you enjoy being with your likely to listen to what they have 2 say, laugh @ their jokes and be generally open around them. You cant really control your body language and if you were to try you would look very fake. Don't get over dramatic with your friends they're just teasing. :)
