See, the thing is, Jake nearly didn't graduate. He found out if he would the day before the ceremony, and only after doing a shitload of extra work for one of his teachers. It may not be a big deal to most people, but finding out that you don't have to spend another year in high school and being able to walk with all of your friends is probably a monumental joy and relief.
Congrats. You did it. Project Graduation was sick.
