ant,
DB your daughters:
Say less than they do.
End exchanges pleasantly - before they do.
Be a Daughter Whisperer.
Be you!

Good news. Good baby steps. I'm so glad to hear this (can't wait until I'm able to report the same "ice-breaking" with beloved StepD & StepS someday.

Peace,

Gardener

With fruit, with weeds even; but gather them
In the one garden you may call your own."
