No use crying over spilled milk
Nathan has decided that when he’s done drinking his milk that instead of swallowing what’s left in his mouth, he’s going to open his mouth and let it all spill out. Nevermind that he may have just been changed into a clean shirt because he did the same thing 30 minutes ago. Nevermind that the milk flows down the clean shirt and onto the carpet and then that, too, must then be cleaned. And oh, guess who does the cleaning? I’ll give you a hint: It’s not Nathan.
