Ha! I knew that rattle snakes love each other.
Harry Greene gave a talk to the Society of Cal Integrative Biology UnderGraduateS (SCIBUGS) back when I was secretary and he was still at Berkeley, and he was all excited to tell us that he had just observed rattlesnake mommies being tender to their babies.

Anyway, I prefer my Mommy any day. Remember elementary school when we didn't buy our valentines but made them out of construction paper and old lace? Well in that spirit of general love, Happy Valentine's Day everyone!
