When my child goes round to a certain friend's house after school, the mum will sometimes drop off a whole hour late and not even phone to tell me. When I text her to ask 'is everything ok?', she just says oh I forgot?! Also sometimes she will say the children are just playing at home, but I find out later they were driving to x or y on an errand (long errands, not a pop to the shops). She will decide to impromptu feed them dinner and not tell me, while I am busy cooking dinner at home.
I am getting quite fed up with it all.
Do I need to chill out more or is the mum being inconsiderate/irresponsible?
