Let's face it, any day that lengthens the dreary month of February is a pretty sad day.
Leap year day is a reflection of our own inability to understand (let alone control) time and space and the universe. The calendar is nothing more than a unit of measure. Time as measured by clocks and so forth is a feeble attempt on our part to gain control of something that is beyond mortal understanding.
We've messed it up from the start. The calendar doesn't quite work so we've had to add this stupid day to "make" it work for us. Now, we have to wait yet another day for this horrid month to be gone.
Do you have a February 29 birthday? Go ahead and enjoy it. But remember: We know how old you really are!
