Dear T,
I told you that would be fine. I was even fairly likely to cancel Thursday's session. But I still feel weirdly upset that you asked this early to replace me with someone else. I mean, I didn't feel right saying no. And if I did say no, I wouldn't feel right potentially canceling Thursday.

And I'm honestly bothered by your comment yesterday that you'd prefer I didn't come in Thursday, even if it was tongue-in-cheek. It's not my fault you have to go to some graduation and aren't working Wednesday. And that you filled up your Thursday schedule. Well, now I guess you're still stuck with the whole 9 hours!

I guess at least this way I don't have to make a decision (I mean, I could have said no to your text, but if I'm already on the fence, it seemed wrong to say I wanted to keep the session).

Love,
LT
