How did friendship change max and Kevin at the end of the book?

It effected them because the really have eachother what they both needed someone and something to believe in. The both gave eachother something to look forward alto everyday which they didn't have before excpecially not Max. AlsO Kevin really helped Mac because he taught him vocabulary and how to write and much more. Also I think Kevin taught Max just how to love and believe in something. I think they saved eachother from gettin pocked on and when they did get pickednon they always over camevthe situation.
Also at the end of the story Max had confidence and dealt he was smart and could write and read books. Also they gave eachother some to trust because betide they really didn't trust anyone. Also without their friendship it really wouldn't be a book the whole book sleuths just be two kids getting picked on their whole life. So their friendship was important very important.
