Alex's humor has began to blossom. Tonight is proof.
Alex: I'm thirsty
Joseph: Well, we will visit the water fountain when we get to Costco.
Joseph: Why not?
Alex: Water fountains don't talk.
Joseph: Ok, we will get a drink from the water fountain when we get to Costco.
Needless to say this conversation had Joseph and I laughing the rest of the way to Costco. I'm sure it isn't as good as hearing it in the moment, but still amusing.
