Hi, DS is 7, a boy in his year a few doors away, call him A, A loves DS but DS not that bothered as A lies a lot - he's made up things like a certain boy broke his glasses and that he's been in fights when he hasn't.
DS has only been over 2/3 times, A's mom is nice enough but I have heard she's fallen out with a fair few people.
Anyway, today DS told me that last time he was there (about 2 months ago) A was telling him about a video he saw on the computer where a grandpa in a wheelchair had s-e-x with a lady
he told DS that he would show him sometime but DS said no thanks, came straight home and never been over again.
Thankfully I've always told the mom that DS isn't allowed on the computer or video games there.
How do I go about telling his mom?
