My sil asked if I could have her granddaughter for the morning tomorrow. She had agreed to look after her, but she goes into town every Friday with my other sil. She knew I was off work, do asked if I'd have gd for a few hours to allow her to go knto town (Friday town trip is something they do every friday).
I've got some stuff I was going to do tomorrow, but it could wait until Saturday. I told her I had stuff to do. She's taking gd into town with them now.
I feel terribly guilty, wibu? Sil does school run for me a couple of times a week.
