"No," responds Gio.
"Well, what are you doing?" I say not believing him because it sure sounds like pooping to me.

Nasal Excavation Reenactment.
"Oh," I say. Who does he get that from? I never grunt when I pick my nose.
Later that night, I ask my husband if he grunts during nasal cavity excavation.
"No, and I haven't had to pick my nose for four days since I've been using Nasonex," Stefan says proudly.
All hail Nasonex. However, I still have no idea where the grunting comes from. Oh well, I guess he really is his own person.
