Some of my favourite memories involve being out with my friends walking around well after midnight, having discussions that would most certainly not be had in the presence of any of our guardians.

> Do you really think it's unreasonable to ask that children out after 10pm (midnight during the summer months) have someone looking after their safety?

Depends. If it's a _child_ proper, like under the age of 14-15 at the _highest_, then no. If they are old enough to be their own person, then yes, absolutely.
