two friends that have such a deeply bonded friendship they seem meant to be.
they share thoughts, ideas, and usually have psychic abilities between each other. they tend to be able to finish one another's thoughts or sentences.
soul friends don't fight and tend to have simliar body parts.
They never miss each other's birthdays...no matter what.
they also sometimes may sound alike.
I think Christine and Drea share a brain because they are always coming up with the same ideas. I think they must be soul friends.
