We have a Polish au pair, who gets my DD1 and DD2 ready for school while I get baby DD3 sorted out. It has been very cold here over the past couple of days and I asked her to make sure the DDs had their hats on. I had to go to the gym early today, so the au pair had to take the children to school. She has access to one of our cars in theory, but doesn't drive, so had to take them on the bus.
When I got back from the gym, the hats were still on the table in the hall, so she had obviously forgotten to put them on. AIBU to want to send her back to Poland?
