Magnets snap toward their opposite and push away their twin. Your best friend might be nothing like you.

Closeness does not require sameness. Often the person who steadies you is the one who fills what you are missing, and the person who grates on you is doing exactly what you do, reflected back. Shared taste predicts less than you think, and what matters more is whether you leave each other better than you found them.

Look at who you actually feel calm around, rather than who matches your profile. If someone irritates you and you cannot say why, ask whether you recognize the habit. Give the person who is nothing like you a real afternoon this week.
