Overheard descending into the Powell Street train station

"That's the problem.  Other people don't kill each other.  We niggas, we kill each other."

"We ain't all niggas."

"We take out a gun, we kill each other."

"You think all Black people is niggas.  But anybody can be a nigga.  A white person can be a nigga.  A Chinese person can be a nigga.  Hell, even an Indian can be a nigga.  Being a nigga ain't about the color of your skin.  It's about something else, nigga."

Then, directly to me:

"What you smilin at, nigga?"
