“My grandpa died when he was 80 – his wife died 21 years before him she was only 55. He never really got over it.
When we were cleaning up his stuff we found an old simple birthday card written by my grandma for my grandpa a couple months before she died. On the back of the card, there were 21 lines written in pencil. Each year, my grandpa would write on the back of the card the date and the year of his new birthday. With a different small note beside it each year. Like, “miss you terribly this time”, or “you would have liked the weather today”.”
