Guys like girls who don't constnatly flirt with them. Especially if you don't know how to flirt. If you don't known how to flirt, or even spell it right, then you don't need to be flirting.
EDIT:
And if you're a guy, that makes it better. Girls do like guys who can spell. And they do like flirting, well, I do :]] unless you're hideously ugly (which I'm NOT saying you are) then most girls (the ones who go by looks as well as personality) won't want you.
