My sister is getting married in 6 weeks time. One of our very good friends, has announced she will be leaving the wedding by taxi at 1845. She says that parents are looking after her children (3 and 8 months) but she needs to be back by 1900. This will coincide with the meal (not cheap) and speeches and leave a 1/2 empty table.
She has always been very controlling in most aspects of her life but particularly so re children (eg. Meals at very strict times etc).
Aibu to think this is just plain rude and not entirely necessary or is this acceptable behaviour?
