I don’t know logic
But I know truth
I don’t know algebra
But I can draw a line
I don’t know calculus
But I know how to drive
I don’t know probability
But I know how to gamble
I don’t know graph theory
But I know who you offended last week
I don’t know knot theory
But I can tie my shoelaces
I don’t know category theory
But I know that a book is sometimes something you read and sometimes a doorstep
