'eighty

I couldn't tell you why we are best friends because you wouldn't understand.
And to be honest, I wouldn't know what to tell you either.
Look at us, screaming down the hall side by side.
We laugh at things that no one even understands why they're funny.
There are songs we sing that mean nothing to everyone else.
And there are those times, where... 
Yeah, you just won't get it.
