9th Anniversary of my Sister passing, Wife not happy

My buddy doesn't celebrate Valentine's Day because his dad passed away of a sudden heart attack on that day. I tried to be logical and tell him that his dad wouldn't have wanted him to mourn the day he died, but maybe to celebrate his birthday, but he won't have any of it.

BTW, my baby sister died of cancer at 37 so I feel your pain brother. Not a day goes by that I don't miss her.
