We were out shopping the other day, my daughter asked for something and I said now. She had a complete meltdown, throwing a tamtrum in the store.
I'm pretty sure she was overly tired because it's been a long time since she did that (she's 10) and usually she takes the word no without too much of an issue.
Because she was causing such a scene, I took my cart to the customer service desk and let it there and left the store and went home.
Have you ever let a shopping cart sit with stuff in it and left because of the behavior of one of your kids?
