So this is weird. I've spent the whole year (okay, a month or two) mentioning, "The cool thing this year is that, because of Leap Year, I get a do-over. My birthday was on a saturday last year, and it's on a saturday this year too."
So your post confused me. How could your birthday have skipped a day, when mine was on a saturday twice?
I finally had to pull out my calendar and look at last year. Turns out my birthday was on a thursday, I just had my party on saturday. And completely forgot that wasn't my actual birthday. Huh.
I'd say my mind is going now that I'm in my 40's, but I think I was always this way. Heehee.
