3yr old Hiding Places

I'm sitting here playing with Ella in the living room. The sound of James grunting slightly wafts in from the kitchen. I turn to look, he has the fridge door open. He is crouched down looking into the fridge.

Mom "James, what are you doing"
James: "Hiding"
M: "In the refrigerator?"
J: "No, not a refrigerator, just a fridge."
M: "Why are you hiding in the fridge? are you pooping?"
J: "Yes"
M: "You are pooping in my refrigerator?"
J: "No, not a refrigerator, just a fridge."
M: "You are pooping in my fridge?"
J: "Yes."
M: "Well, why don't you go hide in the bathroom and poop in there, that is where you are supposed to poop."
J: "OK"

and off he goes, sits on the potty and poops there. Why can't it always be so easy?
