What? There's nothing behind my back.

Here Colin is trying to sneak something inside to the house form the car. I'm not sure what it is but its probably rocks, or at least that's what it usually is.
He thinks he's being very clever and its funny really because I don't mind if he brings something in but he still feels the need to be sneaky about it.
In the end I pretended like I really didn't know he was trying to hide something. I also forgot to check what it was he brought in. Fit in his pocket thought so couldn't have been much to bother with.
