Him: Hey
you (to yourself): Oh my God.. he just texted me.. I wonder what he wants.. maybe he just wants to talk... maybe he's mad at me,i mean, all he said was hey... I should just answer him, i don't want to keep him waiting...well maybe i'll wait another 3 minutes so he thinks i'm busy...no, that's to 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?! i'm just gonna text him back now. Should i reply hi or hey? or hey with three y's? no that's stupid. 2 y's works. He won't know if i did it on purpose or if it was just accidental. Okay. I got this.
Breath in, breath out.

You: Heyy
