Let me refresh your memory a bit. 
I was the one who listen to your problems.
I was the one who took your bullshit. 
I was the one who actually cared about you. 
I was the one who stuck arround even when everyone told me to leave. 
I was the one who stood up for you.
I was the one who loved you even when you gave me every reason not to.
Lastly, i was the one who was there for you when no one else was.
