By far, the birth of my children. I don't think any thing comes remotely close. Maybe this should be it's own OT thread?What was the happiest day of your life? turning 21?, Getting married?, The birth of your children/grandchildren?, graduating from high school/college?, your discharge from the US Armed Forces? having your mother-in-law-move out? I'll bet some of our BY brethren have some interesting stories behind the happiest day of their lives.
