I have two DC at school and a very active three year old.
My friend has just go a promotion at work which means she will not be arriving at school to pick up her DC (who are in the same classes as mine) for about 20-30 after the bell has gone.
She has been flippantly telling other mums that as we have kids in the same class I could just grab them then wait for her to come to the school to pick them up!!
Now in fairness I do sometimes have a chat and hang around for about 10 mins (but not always)
Tbh I don't want the responsibility, we have always helped each other out here and there but this will end up being for the next 3-4 years, every day!
I genuinely think she hasn't thought it through and thinks that as I am there anyway it will be no problem, but if I have to talk to one of my children's teachers after school or rush off as I have something on after school it is going to become a pain.
