So, I thought I’d interrupt this three-class semester to let you know that Mathias played a joke on me at bedtime tonight.  I handed him his sippy cup full of milk, and he turned it over and started sucking on the bottom of the cup.  He waited until he knew I was looking at him, pulled the cup away, said “ha ha,” turned it over and started drinking properly.

Maybe Lisa has had something like this happen before, but it was a first for me.
