Best friends forever

Best friends forever they said but as the boy looked around all he saw was an empty playground. With the schools closed, all the children had left with their parents on vacation. Both his parents had work and were not going.
He went and sat on one of the swings. The slide, and the merry-go-round, all were empty. He had the whole place to himself, but he was not happy. He wished there were other children there.
Likewise, he heard a strange language and turned. A boy was pointing at the other swing and talking. He did not understand a word the boy was saying.
“You want to sit on it?” he said, pointing at the swing.
The other boy nodded his head.
After playing on the swings, they climbed the slide. They talked, not understanding a word that the other said, but that was not necessary. They were both happy, that was all that mattered.
