We have these pretty white decorative rocks in our front garden area. The boys have been told and told not to throw these rocks. Last year this one threw a rock attempting to get silly putty (that was also thrown) off of the roof and shattered the rear window in my van.

Today he made his brother mad and he (other brother) threw a rock at him. This was taken right after, (I was trying to get a macro of the azaleas) the swelling has gone down and he is fine. I don't understand aggression. Sigh.
