Witness

There is a long string tied between two trees. One girl notices the string and adroitly hops over it. Another girl does not see the string, however, so when she walks through the trees she trips and falls. Had there been people there, they all would have laughed. As it was, though, I was the only person who saw it, and I felt it would be rude to laugh at the girl. Instead we just sort of awkwardly nodded at one another, and then the girl hurried along.
