My DS1 has just started secondary school so I'm totally new to this.
He has made a new friend who is travelling in from the outer side of our city by bus (about 20/30 mins away), we live right next to the school. Since the start of term, this boy has been staying in our area after school to "hang out" with his friends. They usually just spend time in our/another friends house or go as a little group to the park which is just behind our house. The issue I have is that he is staying out every night until about 7:30, heading back in the dark and he's been hanging around when my son has dinner, I've been a bit worried about him and have been offering him dinner with us most nights as I feel terrible he's otherwise going from lunch time at school until gone 8 when he must get home before he eats. Each time I ask him he says his mum is "fine" with it but obviously don't know . I know everyone parents differently but 11 just feels very little to be at a "strangers" house for such long periods.
I know at secondary you generally have less interaction/knowledge of parents but was considering asking him for his mum's number so I can introduce myself and so that there is at least a line of contact between us. Is this overstepping or weird or is it just the norm?
