Mike:  Today I'm proud of myself. I remembered to bring along my shopping list.
Victor:  You're becoming an experienced shopper!
Mike:  Gosh! Wrong shopping list!
Victor:  I'm sorry to hear that.
Mike:  But it's okay! I'm sure I can remember most of the six or seven items that my mom wanted me to pick up.
Victor:  Watch out for the cart, Mike!
Mike:  Thanks! You know, as I scamper through the aisles I can always successfully avoid the flying carts of my fellow shoppers.
Victor:  Whew! That was close!
