Mint sighed and walked outside to describe the noise. She leaned on the wall an move her hair to hear the noise better only to hear a screeching noise of blades scratching together like a chalkboar and nails going own on it. "OWWWWW!!" She covere her ears to not hear it but put her hands down and listen again, the screeching was lower so it didn't hurt as much as before though it has whisteing to it. The screeching came from the blade hitting the ground and going along the pavement but if it went along the grass it would have a rough sound. The whisteling sound came from two blades crashing together and slicing past eachother. Mint walked back into the classroom and sat back down.
