Angela,
You've got one in a million there. Hope the rest of the day went better for you.
About thirty years ago, my wife called up one of her best friends and her husband on the occasion of their first wedding anniversary. After the wished them both a "Happy Anniversary", there was a brief silence on the line and a wailed, "We forgot!"
Could happen to anyone.
(But not to me in 36 years.)
Best
Les
