Dear T,
Reading your email now with a different tone in my head. You didn't have to mention how you were looking forward to continuing our work Monday, but you did. And you were trying to reassure me by saying you had no plans to be away this long again in the foreseeable future. I can't expect perfection from you, for you to read my mind. And your wishing me an excellent day--that's you saying you hope I feel better. Does it matter that "excellent" seemed beyond what I'd be able to achieve? You certainly didn't know I had my car in the shop or that I slept poorly (especially as I'd emailed before I even went to bed). Maybe you're just trying to express your wishes for me, that you want me to have a great day, not just an acceptable/tolerable one. Maybe I'm just looking for reasons to be like "f you" because it's easier than missing you. Which I do.
Love you,
LT
