I have two children, one in primary school and an 8 month old baby. DS had parents evening this evening so I had asked my mum to if she could look after baby so me and DH could both attend. We were only gone for around 15 minutes as the school is only across the road.
When we returned, we asked my mum is she wanted to staying for dinner. Once we had finished around, she just got up from the table and said she had best get home. She said bye to the children and then just left leaving everything still on the table. As you can imagine, there was quite a bit of mess as DS2 is weaning and had dropped most of his dinner on the floor.
AIBU that she should have offered to help me to clean up or at the very least brought her plate and glass to the sink?
