I just got home from a meeting at school with my parents about a school trip to America. Everybody going is over 16 - basically, year 11 - 13.
The teacher running the trip mentioned that all students need to be in their hotel rooms at night and not leave when they should be in the rooms.
At the end of the talk, a parent raised her hand and asked "so how are you going to guarantee they stay in their rooms?"
Teacher "well, it's their responsibility, and there will be a teacher on the same corridor"
Parent: "ah right, in the same room with them?"
Teacher: "not in the same room, but on the same corridor"
Parent "...right tuts, dubious looks 
AIBU to think that if you cannot trust your child to stay in their hotel room at night, you shouldn't be allowing them to go on a trip like this? Does she expect us to be locked in?
Maybe I just have judgey pants on today.
