Got an Answer?
No, because I have a friend who does this to me & the excuses are pathetic. She's not too bright because an hour later she'll text a photo of her kid grinning at a cafe at the shops - where we were supposed to meet. It really hurts & pisses me off because she then whines about having no other friends!!
However, I have spontaneously said my children have appointments if this or another friend call in the morning because both constantly want me to run 'urgent' errands/pick up kids etc. Nope.
