I asked my sister if she could collect a large item for me from argos (she drives, I dont) she said yes and told me to reserve it. Anyway she said she would collect it either sunday or monday. On monday she said she would collect it at 5pm, it was bank holiday so was closed early so couldnt. Then she said she would collect it after her appointment today and instead has gone straight home and I didnt really want to have to remind her again as its just sounds like im bugging. I wouldnt mind if she said no she couldnt do it but aibu to be annoyed that she said she would?
