Here is what the plan was. After almost two years of living in crisis (due to various reasons), Boris and I agreed to try to return to normalcy, and as a part of it, to try to live a week without any special events, just doing our usual things.
Boris’s school usually has a midterm week at the end of October, so there are no classes. Also, there are no actual midterms for the courses he teaches, so he didn’t need to be online. That being said, we planned for him to come on Saturday the 23rd (he has classes on Friday) and leave next Sunday.
When I talked to him on Sunday, he said: you know, there is one complication… It turned out that he never checked his schedule, and the actual midterm week was not the last week of October but one before last! There was already too late to exchange the tickets (and in any case, the airlines stopped doing the unlimited exchanges), so now he will have to teach at night!!! Or rather in the wee hours of the morning, both Thursday and Friday, and another long meeting on Wednesday. So much for careful planning!
