So you're faced with something to ponder. Are his good traits enough for you to overlook the ones that are not and accept him as he is, as a friend? Since we are all flawed and have issues in character and personality large and small, can you set aside these things and accept that this is who he is - and be a friend or will you or are you thinking you want to figure out how to change this person's behavior? Because it truly does come down to you. The only one that you can bend is yourself, you can compromise, and accept others because they are worth it or you can continue to struggle with those things you are not able to change. If it's a good friend then find ways to accept and cope with those things that bother you.

There is not a single person in this world that I can get along with 100% and have no issues with. There are, however those that I'm willing to accept their flaws because for whatever reasons, they are worth it as a friend.
