you can't choose your relatives

My mom is coming for Christmas. This is what I offered a month ago. She said no, because she would have to stay in a hotel and didn't want to stay in a hotel. I was relieved.
But on the phone the other night she revealed she has no plans for Christmas. No one had invited her anywhere. I repeated my offer. She took me up on it, hotel and all.
I'm glad she won't be alone the first Christmas without Dad. But this is going to be a difficult weekend.
