Warning signs of what? Stalkerishness o.o?
be very careful
I would never meet up with a guy who I didn't know because what if they are some crazy person. Can't you meet people in your own area? I am not one to be scared of people at all, but I don't think I would even text some random guy if I were you. There really are no sure signs that someone is bad, because they can just lie and act like a totally normal person, so there really is no way of telling for sure. I mean this guy probably isn't some type of crazy person, but is it worth that risk?
If the activity is "texting long distances"! That's a big no no...
Texting says more about a person's typing ability and rhetorical skills than it says anything about their personalities. It means people can pretend to be whoever they want to be while texting. Don't believe anything about the guy, until you have met him.
Being self-absorbed is never a good sign, like the guy I am currently texting with, he's very me,me,me!
Don't fall head-over-heels until you've met face-to-face.
