Christmas shopping could be fun
So I was reading a stepparent confessions Reddit thread, and it gave me the idea that the best possible Christmas gift for SD is art supplies. The messiest, most staining art supplies I can find. Ya know, since one of the items on SDs list of complaints was that we don't have enough art supplies for her. Obviously any gift we get her now will go to BMs anyway. So glitter, paint, etc it is. Water beads. Slime. Probably throw in some candy too - pixie sticks, fun dip.
I hope BM comes home to a huge mess one day and SD tells her to F off (again) when she tells her to clean it up.
