"Heyy, what's up?" This is it, you made the right choice! Or did you? He/She reached out! But what does this mean and what are you supposed to answer? Why does his "Heyy" have two y's? Is that good? Is that bad? Is he texting out of obligation? If I text him back what should I say? Does he actually want me to respond? Should I say "Not much, how about you"? Is that too vague? Should I make an effort? Will he/she think I'm trying too hard? Will I seem desperate? Should I tell him/her what I'm actually doing or is that too much information? Should I answer now or should I wait? Should I wait three hours? Should I wait less? Should I play hard to get and wait more? Should I even answer at all?
