What is that smell?

When I finished loading up the groceries, I walked to the driver's side and opened the door.
A profound smell came rushing out of there as if to say "let me out".

I start sniffing, because that's what a good mom does. She sniffs when something smells amiss.

I smell a foul smell. I can't quite figure out what it is, so my smeller keeps smelling and inhaling.

I ask the boys what that smell is, as it is unlike any other I've smelled.

They grin their innocent grin, look at each other and start to laugh.

I ask again what that smell is, all the while sniffing away.

They proceed to tell me that because it was warm outside, their butts were wet and they needed to wipe them. So they took off their pants to wipe their butts with their underwear.

Hence the smell. I think I'll just stop sniffing now.

Ahhh, I'm so proud of my boys!
