Teens: If you were in bed at night in a hotel and?

An intruder with a ski mask came in the middle of the night and threatened you with a knife saying he will do something with the knife if you don't answer his questions. The intruder asks you what school do you go to, where do you work, where are you from, what's your employers name, what is your birthday, etc. Would you give this information to him? If you say no, then why do you post this information on Facebook where anybody can see it? I use a fake name, a fake birthday, fake where I live, fake employer, etc. Do you get my point. Your Facebook name can be Selena Sexyyy even though that's not your real name. If you post your real name then anyone can look you up and find out your address and where you live.
