My just turned 14 year old and almost 13 year old boys are going away for a week with Scouts (There will be about 7500 other teens (Scouts and Guides) there).
I trust them to behave but feel we should have a chat before they go, on the list so far:
Not fighting!
Girls....
taking care of your stuff
washing regularly
brushing teeth/hair
being respectful to others
trust your instincts
Have fun!
They have been away for 5 days with school, but not both together and have been on many, many weekend camps. Camps are a bit more "free range" than school trips too I think.
It feels different this time as they are that little bit older (and teenage-ery)
Anything else you think needs to be covered?
