This is a L.A.H.F. (That stands for Learned At Home Fact, and it sounds just like laugh.)
If you ever share a bedroom with a three-year-old girl and you come out of the bathroom from brushing your teeth at bedtime and you see her dive into bed and pull the covers over her head and you hear her say, "I not do anything. I really not," then you better investigate your room, because she has very likely broken something or scribbled on the best picture you ever drew with your birthday markers and left the lids off, or else she has put glue in your favorite book.
I just thought you should know that.
And that's probably the longest sentence I've ever written in my life.
