Where's the mustard?

A few weeks ago, ok, so more like sometime in February, Amity learned the "I don't know" gesture while visiting the fam in NYC. She's been using it quite a bit when asked where someone is that she cannot see at the time (ie when you ask her "where's Zara" while Zara is at school) but she's recently started using it as a joke, where she hides something and then gestures to indicate she doesn't know where it is. In this case, we're asking her about the mustard. Which is sitting next to her in her highchair. Funny kid.
