"What happened to your boobs?"

I teach elementary art and music and today a 3rd grade student asked me "what happened to your blues?" He was referring to the blue markers that apparently were all running out, but that's not what I thought he said! My first thought was "well, I'm pregnant so now they're massively swollen and a little droopy". Of course instead, I asked him to repeat the question and then realized what he actually said.
