history: I have had one friend through thick and thin. She could pretty much do anything and I'd stand by her side because she is my best friend. We haven't been friends for too long, but I see it being an everlasting friendship. 
current: My best friend and I haven't been friends for super long, but I believe we will be in each other's lives forever. She's such a great person.
next: I have a friend like that. We lose touch but we will always be great friends.
