Girls are over imaginative

A boy sends a text
BOY: Hey
GIRL (to herself): OMG..he jst texted me..I wonder what he wants..maybe he just wants to talk..or maybe he's mad at me, but all he said was hey.. I should just answer him, don't want to keep him waiting..well maybe I'll wait another 3 minutes so he thinks I m busy...no, that's too obvious. Could this mean he's into me? Or is he just bored? Either way is fine, I mean I don't care if he likes me back. Who said that I even liked him? Huh...I'm gonna text back now. Should I reply hi or hey. Hey with 3 y's? No that's stupid. 2 y's work. He won't know if I did it on purpose or if it was accidental. Ok! I got this. Breathe in, breathe out.
GIRL: Heyy!!!
BOY: plz mark my attendance at college!!!
