Our 17 year old daughter has been responding to personals ads on Craigslist?!!?

My parents would "KILL" me IF I did something like this and I'm 22 years old EVEN!!! But then again, I'm NOT a player!!! So yeah...DON'T bother listening to most of these answers here! She IS looking for ...since she's starting to find it "entertaining"...like she wants to try something new that she thinks is more "fun" in her life! If you don't stop her now, she'll MOST LIKELY turn into a prostitute, due having many guy friends and wants MORE attention from them!!!
