Flirting is a “hobby” that has been going on forever and ever. It is how all relationships begin. But be careful. It can cost you a lot of time and energy if you let flirting take over. You remember the days when you saw a beautiful girl with a nice figure, or a handsome guy with that flexible body, and you just had to show him or her some kind of attention to let them know you were crushing? You remember how you used to always like to go to class just to flirt with that one person? And if they weren’t going to class for some reason, you really didn’t want to go either.
