Need help revising this paragraph

Some folks don’t mind lots of clutter scattered around the house. Others can’t stand that idea. Even doing dishes can be a point of contention. One roommate might see nothing wrong with placing dirty dishes in the sink and leaving those there all night

"clutter scattered" = redundant, wordy

"that idea" = what idea???

"One roommate might see nothing wrong with placing dirty dishes in the sink and leaving those there all night" -- How can you say this concept in fewer words.
