Things that I have thought in the past week that are not true:
1) It's the weekend. In fact, it's Sunday. No store is going to be open.
2) Not only is it Sunday, it's a national holiday. No store is going to be open.
3) Sales don't happen except twice a year, thus there are no sales right now.
4) It's almost noon. I shouldn't go anywhere for two hours in case they close for lunch.
5) The price that is listed on the tag or menu is the price I'm going to pay, because tax is included.
Clearly, I have not left France entirely behind.
