The other day mako-kun, my little, made Missy laugh a lot by indulging in a little Musical Toothbrush Action while we were brushing our teeth.
Here's an example (not me) of the sort of thing I'm talking about.
Missy just laughed and laughed and laughed some more. I love that, and love her. There's something really special about the guileless, innocent, goofy humor my little has. It connects me to something really good, that I don't have adequate words to describe, but love all the same.
