Ohhhhh that’s horrible. So sorry. I know the feeling you had when you opened the door and when you walked away. I’ve had it so many times.
When my friends kids went into my bathroom and stuck their fingers in all my wedding makeup (400£ of Bobbi Brown) breaking my blushers up, squashing the lipsticks by shoving it back in tops workout rolling back down, leaving mascara all over the sink and trying to fill the bottle.
I also had it when I read a story to my eldest last year and then afterwards realised my son had drawn yellow marker pen all over my bedroom wall, chest of drawers, bedlinen, corridor walls, skirting boards and couch cushions.... we had put the house on the market.... first viewing was the next day. It didn’t come off at all so everything has been a slightly yellow tinge since.
I also had it when my eldest son pulled the wick out of my birthday present oil candle and I cannot work out how to get it back in. When he threw my jewellery out of my bedroom window onto gravel (diamond studs and everything).
Um.... what else.... drenching the bathroom. Starting to wash the car with the windows open, throw gravel in the pool repeatedly despite being told sooooo many times not to and causing €500 of damage.
Never know how to deal with it.
