Ds has just come down from a shower with significant dark bruising down both arms. When I first asked I'd only seen finger mark bruising on his lower arm him he said it was from football at school, then I saw the other arm which was the more bruised.
After some discussion he said his friend and him were wrestling & punching each other. When I said that's more than a bit of play fighting, he said they've done it a few times.
I've taken pics but unsure what to do next as D's is insisting it's his friend. This has happened at school.
