["I was trying to get to a loaf of bread in the fridge, and I knocked over a full tub of my mother in law's chicken corn chowder!", 'That must have been messy.  Were you able to get it all cleaned up?', 'Yeah but now the kitchen smells like milky soup! My mother in law is going to be a little peeved too, oops.']
I'm sure she's done something like that in the past herself though.
My mother in law told me not to eat any of her chicken corn chowder before she got home. I tried to move it to get to a loaf of bread and I ended up spilling it all over the floor.
