Dealing with Apartheid

“You’re looking very happy.”
“Yeah, I’m still elated that apartheid has ended.”
“Everybody is.”
“But I’m particularly pleased because I never knew where I was meant to sit.”
“I know what you mean, nobody really thought about how apartheid was going to affect us zebras.”
“Anyway, they’ve changed the system so now nobody cares if you’re black or if you’re white, apparently everybody’s to be considered grey.”
“That’s all well and good but I’ve been told that there’re fifty shades of grey.”
“So?”
“Well, it seems that all the light greys have to sit at the back of the bus.”
