It's good to clean up after your animals.
Dylan is at home with his dog when it takes a poop in his living room behind the couch.
Dylan wants to have people over for dinner.
Dylan finds the poop and disposes of it mopping the area before his guests arrive.
Dylan ignores the mess left by his dog and his guests arrive for dinner.
The guests are left unbothered and everyone proceeds to enjoy their dinner.
His guests arrive and notice the smell, but are left to sit in uncomforted with the smell so as to seem rude.
