I worry the valet will scratch my car

17. I would no longer eat leftovers. Come to think of it, I would no longer place leftovers in my refrigerator. In fact I would no longer have use for plastic wrap or aluminum foil.
18. I would no longer put up with dull knives, dull scissors, or dull people at cocktail parties.
19. I would no longer borrow my neighbors snow blower. In fact, I would no longer personally remove snow from my driveway or anyone elses. Or even the walkway.

Sunpass

Costco
