It may be terrifying, but it's also terribly important. If the friendship can't survive differences, you're going to silently censor any points of differences (real or imagined) and soon you're just pretending to be the people you think the other expects you to be. No depth of connection, no growth.

You want someone to be friends with you, as you actually are. And that means you need to be friends with them, as they actually are, even if you worship different brands or vote for different movies.
