1 idea for a storyboard

The first story is about not living rubbish in the park. I group of teenagers went to a picnic and behind where dey was sitting there was a family. The teenagers were living and they left rubbish and broken glass behind them and the little girl kicked the ball near the broken glass and she stated the glass and har her self. There will be like a rewind when the teenagers picked the rubbish and the glass and put it in the trash bin and the girl didn't get hurt and she continued playing.
