A "boy/girl" friends you through Facebook. He/she is exactly your age, likes the same things as you, likes the same music you do. After a few weeks of chatting, he/she asks you to meet him/her. What do you do?

I'll tell him/her that we can not meet because I don't know if that they're really who they say they are. It's a wild world out there. Anybody can be who they want to be online.
