DSS just turned 18. My DH is working away right now but DSS has been coming to visit. DH bought him a car that needs work before he left so I'm sure he will be coming over eow until my FIL gets the car fixed. DSS asked FIL if his friend could come spend the weekend. My IL's and I are not comfortable having a kid spend the weekend with us that we don't know so FIL told him no. This kid is around 16 and DSS has just recently become friends with him. DSS asked FIL again and FIL again told him no. So DSS said he is going to email DH about the friend being able to spend the night. Do you let your DSC have sleep overs at your house and would you let an 18 yo DSC have sleep overs?
