Well then, that's awesome ! Happy Birthday to you, Miss Spoochy McGoo !
Age and birthdays are only relative, so, just treat it as a special day honoring you, not, as a Bday. Which, is the way I try to think about it. However, usually, mine falls on a work day and is like any other day of the year. I suppose you could forget Memorial Day and think of it as a day that everyone across America is holding parties in honor of you :)
