It's no secret I can't remember their birth years. I remember all their birthdays, that's what's important. I can figure them out through a process of elimination. My oldest was born two weeks before our first wedding anniversary, the youngest is 7 years younger. Now I just have to remember when we got married. I graduated college in 1985, proposed on Christmas Eve that year, and attended Officer Basic at APG Maryland. We had a 1 year, 4-month engagement. so were married in 1987, daughter born in 1988. Second daughter born in 1994.
And yes, I had that all wrong and just ask my wife for the correct years.
