Not an AIBU but want to know WWYD.
In Ireland, we've been allowed to have socially distanced garden visits if someone lives less than 5km from you.
Me and ds visited dsis and her ds. The kids were playing in the garden, they bumped into each other while running and my dsis ds fell and cut his head. He had to go to a&e which resulted in a hospital charge for them.
Dsis has said not to worry as accidents happen with children, but I feel like I should pay for at least half of the hospital bill. In my situation WWYD?
