We were invited over for early evening drinks recently at a friend's house 5 minutes walk away. My 11 year old wanted to stay home but we made him come as we didn't know how long we'd be (possibly 3 hours plus).
He has stayed at home by himself up to 2 hours before but this seemed a bit too long and the fact it was evening time and dark made me think he shouldn't be left.
He feels that this was very unfair and he should have been allowed to stay home alone. Would you allow your 11 year old to stay behind? When at home by himself, he goes on his devices or reads and we've gone through safety/emergency what ifs. In the end we were out about 3 hours.
