You: hi

Stranger: anyone here ?

Stranger: hi

You: I can already tell, you're a guy.

Stranger: yep

You: You used a space after the word "here", before the question mark.

Stranger: and u 2 right ?

You: I'm a psychology major

Stranger: well ...really..?

You: The 2 dots after the word "really" and before the question mark indicate that you have 3 testicles.

Stranger: so u r doing psychology work here ? hOHO

You: No, I was just pointing out the obvious. How old are you?

Stranger: just from the fucking “space and dots” ？

Stranger: u can tell me then how old am I ?

You: That's impossible to tell through this kind of psychological evaluation. However, after reviewing your grammar I'd say you are between the ages of 15-18

You: .....and you're a minority.

Stranger: u r fucking wrong my friend.. im20


You: I'm not your friend, buddy!
