I missed an anniversary date recently. (Fortunately, my husband remembered and got the card out in a timely manner.)
As the family historian one would think I would remember birthdays, anniversaries, etc. After all, a day rarely goes by when I don't work with dates of some sort.
My daughter quipped that maybe I should just focus on important dates for the living family members! Ouch!
(I'm sure I'll convert her to the genealogical way of thinking one day!)
