Just because you don't agree with someone doesn't mean that you can't get along with them. You can even laugh together! If you always opted out of being friends with people who think about life differently from you, you'd miss out. The back-and-forth debate in this relationship creates an exciting intellectual reward, and that has a valuable place in your life. You have so much more to offer than just your congeniality, and people are just as attracted to your rough edges as they are to your smooth ways.
