What?

At least once a day, the following occurs: Eli and I will be talking about something in front of Tommy, but not really with Tommy, and he'll yell, "WHAT?" And if we don't immediately stop talking and respond to him, he'll yell again, "WHAT? I don't know what you're talking about!" And then, just because she can, Lizzie starts saying, "wha? wha? wha? wha?"

Sometimes it makes me crazy, but usually it makes me laugh. It inevitably means that Eli and I don't finish a conversation, and sometimes it's a conversation we needed to have, so that we can discuss manners and interrupting as a family.
