This was written for the Trifecta Writing Challenge . I took the prompt literally and went back to a memory from elementary school.
"This weekend we're asking you to harken back to your grade school days and write a haiku (an unrhymed verse form of Japanese origin having three lines containing usually five, seven, and five syllables respectively)."
At Recess, Alone
Children play, but one
doesn’t join. She walks, content,
beside her own thoughts.
