Imagine that Timmy and Jimmy are selling lemonade on the street outside of their parents´ houses. Timmy and Jimmy are both selling three to four cups of lemonade every day. Every few days they increase the amount of sugar in their lemonade and put up signs that they now are selling a new type of lemonade.

This usually brings in lots of new people, but some are starting to get confused as both Timmy and Jimmy are selling so many different brands of lemonade.

Now Lisa moves into the block. She spends some time in her garage trying different lemonade flavors until she finds one she really likes herself. Then she goes out on the street to sell the lemonade.

People really like Lisa's lemonade. Its taste is distinctly different from Timmy's and Jimmy's. People start telling their friends about Lisa's lemonade! Soon people from the other block are starting to take the two minute bicycle ride just to get Lisa's lemonade!

When Lisa after a few weeks introduces a slightly refined version of her new lemonade she sells as much lemonade in an afternoon as Timmy and Jimmy together sell in a month!

After a while Timmy and Jimmy get angry. One night Timmy sneaks over and steals some of Lisa's lemonade. He moves his stand right next to Lisa's and even put up a sign saying "Lisa's lemonade" on his stand. The next day he shows up wearing Lisa's clothes.

Some of the customers get confused and accidentally but Timmy's lemonade instead of Lisa's.

Lisa goes home and cries to mommy. The parents get together and decide to ban Timmy from selling lemonade out on the street.

How's that for context?
