It's a best friend but more. It's the one person in the world who knows you better than any one else. That someone who makes you a better person. No, actually they don't make you a better person. You do that yourself because they inspire you. A soul mate is someone you carry with you forever. It's one person who knew you, accepted you, believed in you before anyone else did or when no one else would. And no matter what happens, you'll always love them and nothing could ever change that.
