I'm posting to vent as I don't want to cause an atmosphere by being in a foul mood here at home.
Dss(16) was sitting on the floor next to ds1(9) playing a game on his phone. As he finished up and closed the game down I happened to glance over and saw that his screen saver was a picture of a naked glamour model. Just as I glanced over so did ds1, but I don't know how much he saw because I tersely said dss' name and he quickly put the phone out of sight.
Dss a lovely lad but can be very thoughtless. He and his df, my dp, moved in 6 months ago. I spoke to him about it and he readily apologised and has taken the picture off his screen saver. He's brilliant with my dss', really kind and caring, but I worry about him inadvertently exposing them to inappropriate things. He sometimes talks openly about his defiant behaviour and anger management issues at his old school and has to be reminded that it's fine to talk about those things with his dad and me, but not when the boys are present. They look up to him and I don't want them to copy. He loves college and has no behaviour problems now, and during his high school years never exhibited any challenging behaviour at home. I have no doubt that he respects the boundaries set at home and understands why they are in place, but it's the potential thoughtless incidents that cause me anxiety.
I'm not sure if there is anything dp and I can do any more than we are already doing, which is keeping lines of communication open and respecting that the transition from being the youngest in a household to being the eldest can be difficult.
Any thoughts on the situation are most welcome.
