Glue

Youngest Child was far too quiet, and I took a trip around the house to investigate. I came upon my bedroom door, closed, and tried the handle. Locked from the inside. Little bastard. So I went and got the metal skewer that I use to jimmy the lock in such situations (yes, it's happened before), and found YC sitting on my bedroom carpet, covered in Elmer's Glue, using a paintbrush to mash it into the rug. How cute.

God makes children cute so we don't kill them. It's a natural defense mechanism.
