Both. We're different in ways that compliment each other. But we're similar in ways that let us at least have a good conversation and some fun. Most of my best friends are pretty different to me, and a few of the people I've considered enemies have been kinda similar in some ways, but with different goals. Then there are people who are so completely different to me, I don't think there's an inch of common ground between us. People like Robotnik, who I'll never get along with.
