not the way to make a sale

maybe i actually do use my vacuum cleaner because it was full of nastiness that i was pulling out in front of my house. a door to door salesman came by and looking at what i was doing and im sure trying to make conversation said 'oh, do you have a dog?' 'no,' i said after pulling out another hair ball wrapped in lint, 'that is all me.'
he ran off then. surprise, he didnt make his sale.
