I was a smarty-pants and said it was a day that was so darned busy I didn't have time to call them until I got home, and I wasn't home yet (it was 8PM). It was a day when everyone said "Oh, it's Friday the 13th" and I said "It's my Mom & Dad's anniversary! They've been married 44 years!"
Here's what a wedding reception in 1970 looked like:
Happy Anniversary Mom & Dad!
BTW, Mom - you've been married for 70% of your life... Congratulations!
Also, how did you get your hair so high?
