My friend let her dd have a friend stay overnight.They slept in the same roon,seperate neds.Her dd insists they are only friends and was shocked her mum thought otherwise.I suggested her dd may be being very clever, but really don't know.
They do seem to have a lot of platonic relationships with the opposite sex ,much more than we ever did.
Dh said every 15 yr old boy would want to shag and he would only allow it if the boy was gay.
