Am trying to make decision:

Mr. Squirrel switched courses with me, solely to make my schedule easier.
After we switched, the course he took from me was cancelled.

Financially, we're both okay this semester. This course basically allows whoever has it to put some money in savings. (Yes, we're somewhat financially merged, but still mostly not, for various reasons. There really is no "our savings," yet.)

It seems logical that he gets the course back, doesn't it? I offered immediately when all this first happened, and brought it up again today -- the course is tomorrow. It's not a class either of us has to do much prep for, obviously.
