Ugh, @Laura2592 , I had one of those the week after Christmas. She IB'd two days, a Monday and Tuesday, but "really wanted" the Friday/Saturday, and although I was firm that those dates were booked, I kept getting the reading-between-the-lines feeling that she and the boyfriend (and dog! - yet another parallel) were going to show up Friday anyway.
It turned out, nearly immediately, that I didn't need to do anything. The province went into yet another lockdown on December 26, and no one got to go anywhere.
That works, but I can't recommend hoping it happens for you. 🙂
So, yes, this has decline written all over it.
