I taught a student this week who came back for a few lessons after a six-month hiatus, and I let him know that there was space for him to return on a permanent basis if he wanted to do so...
ME: So I can definitely make a space for you if you want; I had one at the beginning of the year, but you didn't take it.
KID: I was gonna come back, but I thought I knew everything...and then I
went to All-District, and I heard all these people doing all these
dynamics and things, and I was like, "Crap! How do you even do all those
things in one measure? It was like a sucker punch!"
