Boys are 9.
Is it better that I just don't allow my son to go to their house because I don't agree with children this age playing COD and Fortnite, or AIBU to ask the parent not to allow my son to play? Or just trust my son to not play (would be an odd play date in that case).
The only time I've done similar is with DS1 (now 19), when I said he wasn't allowed to go on friend's trampoline because it didn't have a net.
