A close friend but better. Usually someone you are very close to and can
trust with anything. They are there for you when you are down and
depressed. They will wipe your tears and cheer you up. If you've had a bad
day, they'll call you that
day or the next, to make sure your alright. They'll stick up for you, and will always have your back. They'll give you good advice and you can talk about anything. When you get in a fight with them, you can almost always forgive them. If theres a problem and you confront them about it, you may both be
pretty upset but in the end it will all work out..and if not.. then they aren't much of a bestfriend.
Most importantly your yourself around them. And they love you and you them.
