After Adam left for work this morning I noticed that a garbage truck was in the street and he hadn't taken out the trash. So I ran out with a garbage bag to make sure it made it to the truck.
I've been cooking and running errands and tidying up during the day and it suddenly occurred to me that I've become my mother. That's what she does when she visits me - she 'takes care' of me. I think I'll just let her do it in the future, without protest, because I'm realizing that it feels good to do things for your children when you visit, even when they are grown.
I guess it's just a mother-thing.
