Once had an unlucky Saturday the 13th. My 16th birthday in April 1974. Family forgot. Not exactly the 16 Candles scenario. Dad out of work and depressed. Mom overworked and worried.

Actually was more unlucky when they did remember a couple of weeks later. I felt so bad for them. I was a bit pissed that none of my siblings or extended family or friends remembered. But I was very good at being invisible.
