I love kids, y'know that? While I was at the grocery store picking out vegetables, I had this exchange with a mother and her two children in a kiddy-cart:
Kids: "Helloooo! Helloooo! Helloooooo! Helloooooooo!"
Me: "Oh! Heh, hello!"
Kids: "Heloooo! Hello!"
Mom: "He already said hello guys, you don't need to say it again."
So obviously, when they turned to leave, I knew what had to be said.
Me: "Goodbyye! Goodbyyye!"
Mom: "Oh, he's saying goodbye! Can you say goodbye guys?"
Kids: "Goodbyye! Goodbyyye!"
I spent the entire second half of my workday reading Calvin and Hobbes strips, and I think it shows. Thar was just the sort of levity I needed to lift me out of a day spent sick.
