Who shoveled the walk?

Allison and I were eating lunch together the other day when we had an interesting conversation...

Allison: When did you shovel the sidewalk?
Me: (brief pause while i think) well, last time it snowed i guess.
Allison: No, I mean the sidewalk by the street.
Me:(pause again) I've never shoveled that one.
Allison: Well somebody did, I saw it was clear this morning from Makenna's room.

I go to the window, look out, and this is what i see....

(the walk under investigation is just past the real estate sign, under the snow pile)

Apparently she had seen the little patch of grass along the far walk and decided the walk had been shoveled. Very funny.
