My DD is 14 with a busy schedule of after school activities during the week , including Saturdays and Sundays . On Fridays we let her bring some friends over for pizza and movie , as it’s her time to “ chill” . We live in a relatively big house and they mainly stay in the garden or in the games room downstairs they don’t really bother us , she Keeps them out of the way and sometimes I even forget they are there. Most of them leave leave relatively early . However, one of the friends doesn’t seem to have a curfew to go home. Sometimes it’s 11pm and the friend is still at my place. I have to prompt her to leave every time, and my DD gets in a mood with me., accusing me of being rude . Should the friend’s parents give their teen a time to leave my house ? Or should I make it clear from the beginning? They all go to the same school and are local to us but I haven’t met the parents as when they do come to collect their teen they don’t even knock on on my door to introduce themselves. I find it either ODD to say the least . Just wondering what other people would do if they are in my shoes?
