Aha! It's not just this one T, the one before that cared too? Looks like a pattern to me. I would do the school T, tell yourself it's just for summer, save a bit of money (as if you're saving for a house or other large-ticket, valuable item you want) and look forward to seeing T later in the year and showing her all the neat stuff you'll have learned in the summer?

I didn't see my T for 9 years and then saw her again and that was one of the best things that has ever happened to me in my life. Why? Because of how we had BOTH changed and how much better we worked together than we had before. Think of this time as a move forward and a chance to broaden your experience and show yourself and your T what you're really made of?
