Assuming no clubs/deviating into town/to a mates house.
If they finish school and just walk or get the bus or train home, how long does that take?
Ds1 gets in just before 5pm. There's a 45min wait for the bus and a 50min bus ride. He's OK with it as the stop is just over the road from home but I do wonder sometimes if there is a better way. Technically I could find an hour to go pick him up and drop him back before I carry on. It's not ideal though and would ruin his cred with his mates. He's 13 in Year 8.
