Promise

Joey isn't eating like he should, so I told him I was going to call Gramma who would be very disappointed.

Luke, his big brother was sitting by and pointed while saying "ohhhhhhhhh!" to Joey, to make such a punishment seem twice as bad.

"Stop it!" Joey yelled at him. "What if YOU were little and YOU broke a promise and someone said OHHHHHHHH to YOU!"

His panic was apparent, and made his Gramma laugh.  Don't you dare break a promise Joe!
