(Cicero, On Ends, 2.102)
"I have to admit that these are the sentiments of a good and humane man. But a wise man, and especially a natural scientist, which Epicurus claims to be, should not be thinking that anyone has an anniversary. Can the identical day, once it has occurred, occur time and again? Of course not. A similar day? Not even that, except perhaps after an interval of many thousands of years when all the stars return to their original positions at the same time. It is not the case, then, that anyone has an anniversary. 'But the anniversary of his birth is observed!' I am well aware of that! So be it."
I think that's as close as we are getting to Cicero wishing you a happy birthday.
Have a great birthday, Joshua and Kalosyni!
