Caught in the act

Luke is known to steal food, especially if it's something sweet (candy, cookies, cupcakes, etc). Mia made the mistake of leaving her partially-eaten chocolate cupcake unguarded within Luke's reach. He grabbed it sneakily (is that a word?) and went halfway downstairs to eat it out of anyone's sight. This picture is right when he noticed I had caught him.  

Then he tried to win me over with a smile.

Once he realized I thought he was funny, he chose to show off his spoils. For the record, he left a Hansel-and-Gretel-like trail of chocolate cupcake crumbs all the way down the stairs, which I vacuumed up later.
