Four people are sitting around a campfire after a long day of recreation, when one man comments: "Do you realize that around this campfire, the four of us include a mother, father, brother, sister, son, daughter, niece, nephew, aunt, uncle and a couple of cousins"?.
If everyone is related by blood (with no unusual marriages) how is this possible?

mother & father are sister & brother
they each have either a son or daughter
