She was at a park with X and OW and apparently ran into a girl from school she'd had a class with, and couldn't remember her name and asked her what her name was again and that really upset OW. OW went on and on criticizing D15 about her social skills.
Actually, I think this shows incredibly GOOD social skills on your daughter's part - how many of us are afraid to just fess up and tell someone we forgot their name?
You might try working with your daughter to come up with some good all-purpose comebacks for OW - she can write them up on an index card and stick them in her pocket for reference.
OW may be especially touchy right now BECAUSE her daughter's been in rehab. She may be extra worried about what will happen to both girls. Or she may be having problems in her relationship with ex and it's leaking out in this way.
