Later in the evening I was inside doing some work for me "real job" and the boys asked if it was okay for them to go outside and play basketball.

Sure, why not.

About five minutes later I heard the DISTINCT sound of a golf club connecting with a golf ball and saw both boys running to the empty lot to go find it.

I watched from the window and saw BOTH OF THEM intentionally disobey me.  This drives me NUTS.
