"Because I'm your sister, and it's my job."
That's what I tell them when I'm being a snob.
"Because I'm your sister, it's what I'm here for."
Then I go away and slam the door.
"Because I'm your sister, so I'm a snitch."
That's what I tell them when I'm being a bitch.
"Because I'm your sister, and I love you."
Hey, at least that much is true.
