Dd is 15 and started seeing a boy who is a year older. We have met him as he came to our house last weekend. He seemed a nice boy and was polite and friendly. He has asked her to go to his house this weekend. We told our dd that if they went up to her room the door must be kept open and we were home the whole time. I’m just a bit concerned how I check that his parents are home and if they will be allowed in his room. How do I check this out?
