DS(15) came home from school very annoyed yesterday, he said he was put into isolation for having a drawing on his hand/wrist. He got bored so he drew on his hand with a pen, but it's not just scribbles.
Apparently, he was told to go to the toilet and wash it off and he tried to but it wouldn't come off so they sent him to isolation. He tried to get it off at home and it wouldn't, I tried to this morning and it slightly faded but it's still there.
Aibu to think this is ridiculous?
