I heard this somewhere a long time ago. I think it was Stephen Fry, but if it was, I have no idea if he was quoting someone else or if he made it up.
I love Stephen Fry.
“There are two types of people in this world. One who thinks there’s two types of people in this world and the other that knows better.”
I know it sounds trite, but I think it does us all well to remember that.
