Oh, crud.....I didn't thank my high school band teacher for the recommendation she sent me for Bishop's, or my private clarinet teacher either, and that was four years ago. Of course, in the case of my band teacher, she hated me to begin with (but couldn't deny that I practiced every day, showed up to every single band rehearsal on time with my part prepared, and volunteered at all the events I could), so maybe going to a school about 900 miles away from her was all the "thanks" she needed, lol.
