Facebook chat questions from a guy?

[Jon]

What does it mean when a girl sends a lot of smileys?
Is it creepy or odd if a guy sends messages like ‘hahah‘ or ‘‘?
How can I tell whether I should continue a conversation or not?

Well, if he starts acting shifty and suspicious. Then either block him or delete him, you can never trust anyone nowadays... by suspicious i mean like millions of kisses and hearts and if he asks you to meet him say NO. You probably know this, but im reminding you just in case... hope this helped, sorry if not :/

She's probably just being nice! Putting a smiley isn't really a big deal.

So no, it's not weird to send an occasional smiley or say "hahaha"....it may actually make the conversation seem more normal and flow better.
