Ds just returned from a day out with his best friend and family for a walk and picnic in woods. They picked him up this morn and i sent him off with a rucksack with his wellies etc in,and gave the mother a 10note to buy the kids ice creams . She's just returned him now saying 'its just as well u sent that tenner ...u forgot to pack his packed lunch! We used the tenner to buy him some chips from the van!' Now, when they invited him for a picnic AIBU to expect they would provide the picnic for Ds, not just themselves?! I've fed their son hundreds of times! Can't believe they couldn't spare him a sarnie ! And they didn't buy any ice creams with the tenner, just the chips, and i didn't get any change! Not that i would ever have expected change, but really, AIBU??
