I need help; I might have a creeper on my on Tumblr?

[Tarryn]

I'm on Tumblr and this guy is very interested in me for some reason.

He's 20 [or so he says on his profile] and he says his name is Brian. He's shown a picture of a school yearbook of "him" and it says Brian. But he could've stole that and is using Brian as an alias or something.

I don't know why, but he's VERY interested in me! He talks to me a lot, and says he has a lot to show/ask me and seems to want to get to know me. He COULD be friendly since we're of the same ethnicity, but he's creeping me out a little.

I'm only 17... I know the age gap isn't big at all, but even I still consider myself a little kid. I'm just a little girl! And even when I'M 20 I'll just be a big kid! [this is just my worldview based from my culture]

He's never asked for my phone number or where I live, but he ALWAYS wants to talk to me. Help? I'm a little scared!

Your a smart girl. Don't ever trust anyone that you don't know online. My suggestion you just tell him to leave you alone, you don't like talking to anyone that you don't know personally. If he still bothers you after that, tell him that your going to tell your parents about him bothering you. That will usually scare someone off, especially if they are a predator.

Don't trust anyone you don't know personally.You can chat with him, but don't give him any personal informations,your adress or for example don't tell him such things like "I'm going for holiday for 2 weeks."He might be thief and if he lives around you (maybe that's it maybe he is someone from your school who likes you but you don't) and then rob your house.
