slow children at play

Today i was with a driving student in a quiet residential neighborhood in Upper Arlington. As we drove down the street i saw 2 early teens with a 4 square ball standing right next to a sign that said "slow children playing" We came within about 50 ft. of the teen, and they walked out into the middle of the street and bounced the ball and jumped in the air slowly waving their hands. They made us come to a hault and proceeded to play in slow motion for about a minute. I thought it was hilarious
