Jonas and Giver come up with a plan to escape from the community meanwhile when he leaves the memories will stay and the people will get the memories and be able to have feeling and not live a life of sameness.
      The only thing is the Giver can't leave with Jonas he must stay because if he doesn't the people will suffer from the memories and won't be able to live through it and would most likely apply for release.
I have been in the same situation as Jonas where I had to give up something to get to something greater, me and my friends always played 78 precinct basketball together but when I made the travel team I started playing there and didn't go back to 78 in house because it wasn't much of a challenge but the travel league was and I liked playing in it a lot more. It improved my basketball skills and teamwork skills . Sometimes it is better to move on from something your familiar with, just to increase your social skills and explore new oppurtunities.
