The box: 100wc week 16

Suddenly out of nowhere a box flew in front of Zac.
“Hm where did this come from. Maybe it fell from the sky, no nothing falls from the sky anymore.” Zac was curious about the box. He wondered where it came from, he already looked inside it and inside it was a ball.
“A ball,  ripped off, but where did it come from?”
He looked for the person and then he found a trail, a trail of
paper. He followed the trail and found the person.
“What, Bob why did you through this box in front of me.”
“because it’s yours.” said Bob yelling.
“oh yeah it is.”
