This person does not have to be related to you by blood. They are someone you cannot live without. You've made that instant connection and it's over. Twins for life. You may get angry or upset at them but they'll always have your back and love you for who you are. You can tell them everything or you can tell them nothing, but they'll understand you regardless. You're more than friends, but less than the other.
Twin 1: "I love coke."
Twin 2: "Oh me too!"
Both: "Twiiiiins!"

And it goes uphill (or downhill) from there.
