Theres this girl I text who always responds immediately. Within 3 minutes, the only exceptions being church and sleep. When she's busy the reply is a "hey", an exclamation mark or two, an address to whatever conversational thread i may have started, and then saying what she's doing and that she can't talk.
My normal reply is just something along the lines of:
Got it. Talk to you later bud
I do know this girl is totally into me. I honestly think I'm overanalyzing this one, but I figured theres no harm in asking you guys to weigh in with suggestions and comments
EDIT: She always texts back when she's free, but I doubt that has anything to do with my response
