I ran across this one lately, all I remember is that I took at at Busch Gardens in Tampa, eons ago. And although I don't know the genders of the respective animals, it seemed to me a marvelous metaphor on the nature of love. How you would express it in words, well....I have my ideas, I'm sure plenty of other people could say the same, ergo it's probably best left to the mind of the individual beholder. Have at it.
