Quite a good Grab shot! So to speak. Looks like you have enough evidence here for a conviction! Seriouslly though, It's a well captured moment. Well Done!

What facial expressions. Ah, the dynamics of sibling relationships. I have two boys, and what I tell my oldest is, "What goes around, comes around". Not sure if he fully comprehends that yet... but he will.
