Pre 18 school trip info “Bring plenty of water and remember we will only release students to a known adult at the end of the day”

When you ...
... keep emailing them the details of the local sex health clinic.
... hide your gin from them.
... thank them for loan of their car.
... "borrow" their hoodie(s).
... say how nice it would have been to have their (large muscles) company on the train when that drunk commuter looked like he might get feisty.
... they offer to fix your car.
... they pay all their own bills (!!)
