When you have a best friend, you'd go to the ends of the earth for them. Drive them home if they're drunk, bail them out of jail, murder someone for them. Yup, there's really nothing best friends won't do for each other.
Then there are those friends you wouldn't trust to walk on their own two feet, the friends that seem to only be there just to mess with you. They're not best friends, but sometimes, you have to take what you can get.
