I have a brother and a sister...the brother goes to pre-school only in the mornings twice a week. On those days mom comes to pick him up and drops him off at pre-school, and then picks him up and drops him off at my house. We live in a small town where pre-school is about a 2 minute drive to/from my house and mom's work is about a 5 minute drive to/from my house. Mom never asked if I do school runs so it was never an issue, and I would have said no anyways seeing as I don't them.
