My parent had this rule of shoes in the house, (not sneakers or outside shoes, but crocs or slippers) my 6-year-old self disobeyed constantly because I didn't like wearing shoes, but one day I got up and started dancing in the living room where we had an unassembled bicycle stored until we could build it that weekend. I ram my nail against one of the spikes in the wheel and my nail came clean off, we had to go to the hospital and I missed a birthday party i was looking forward to. This time made me more cautious of whether I should disobey, and now I'm 14 and there won't be a day when you find me barefoot in my house. The End.
