This is an assignment that I did in my writing class. It is simple: create a sentence that is at least 100 words long, that is grammatically correct, and without any run-ons. The idea was to start with a base sentence, and then work out from there. Here is my sentence, and I challenge you to try to write your own, and if you are so inclined, post them in the comments below.
The Monster Sentence
When we think about those who are dead, we think about different things: about the little girl at the end of the street who fell into a pile of leaves—hitting her head, and while unconscious, being run over by a teenage girl who was too distracted by a text message from her boyfriend to notice—taken before her time, about the brother who died in a foxhole—fighting a war in the Middle East against men of the sword and crescent for black gold—by jumping on a grenade to save the rest of the men in his unit, or—like me—about a grandfather stricken with cancer—living in agony for months and months, unable to care for himself—who finally passed away—putting an end to his suffering.
