I have just come back from a couple of days break with my kids, nephew and SIL. During the time I was there, nephew threw a watermelon down my top, blew chocolate milkshake all down my back with a straw (encouraged by his mother and then laughed at), threw my trousers in the swimming pool, filled one of my shoes with water, dragged the mattress off my bed and threw the bedding all over the room and ripped up a book of mine.
Most things encouraged by his mother.
I told my brother when I got back what his son had been like and it's apparantly caused a huge argument between him and his wife.
Was IBU?
