When I'm...FOUR.

So there are many things we've told Porter he has to wait until he's four to do: use a scissors, use a knife & chew gum. Tonight our realtor stopped by with some paperwork for us to sign & he was talking about his daughter. I asked how old she was & he said she was four. Suddenly, out of nowhere, Porter asks "Does she have gum?" He heard the magic number FOUR & just had to know if it was as good as he is hoping it will be.
