Ed, a business person is a friend of Fran, the owner of a candy story. Every day, Ed spends a few minutes in Fran's candy store, looking at the candy and usually buying one or two candy bars or other candy. One afternoon, Ed went into the store, looked at the candy, picked up a $1 candy bar, waved the candy bar at Fran without saying a word, and left the store.

1. Is there an enforceable contract between Ed and Fran? Why or why not?
2. If there is a contract, what type of contract and how was it formed, specifically?
