1. Linear Algebra and Multivariable Calculus as a thing in my life; the discipline will continue quite happily without me.
2. My relationship with TP; a.k.a. a whole set of dreams and goals and commitments I made to another human; a.k.a. the most significant adult romantic relationship of my life.
3. Another year; today is my birthday.
I'm sorry, I haven't been able to muster the emotional energy to write here, there has just been too much.
