A similar experience I had was when I saw my mom cry and pay respects to my grandpa for the last time as he was sent to be cremated.

I respected my grandfather but as we lived half way across the world, I wasn’t emotionally attached to him and didn’t feel very sad. But seeing my mom, usually a very silly lady and a very strong, loving grandma herself, turn into a daughter saying goodbye to her dad in tears for that split second broke my heart.
