"I can't believe he left us here with nothing but some sponges and a bucket of water!" Ron replied[replied, answered, agreed. try not to repeat words in a story too much, or it will have a repetitive feel,]cleaning a desk.
"I bet you the four of us can come up with very good reasons that Snape is the absolute worst!" Harry answered, scrubbing something off the ceiling.
"Ten? I can come up with 50!" George replied, also scrubbing at the floor.
"Lets have a go at it then." Fred responded.
"One: his nose is so big you can catch fish with it." George said starting the list wile grinning.
"Good one!" Ron laughed as he attempted to get rid of some dubious-looking green stains on a desk.

"He is absolutely horrible to us," Harry added, still scrubbing at another desk.
"He caught me and George designing fireworks last week for the shop and gave them to Filch." Fred said, dipping his sponge in the water.
"He's making us clean the classroom with nothing but a sponge" Ron added before looked up and screamed.
