Amazing things come in fours or a quartet. Barbershop Quartets make great music. So do the Beatles and a bunch of other four-piece bands. Four people usually anchor your news programs at night. I grew up in a family with four people. In “Sex In The City” we saw a quartet of women light up the screen with friendship and a lot of glam. Four basketball teams are left in the college basketball tournament. There is something interesting about the number four or a quartet that makes things just even, just square.
