I'm sorry for your loss that sucks but at least got to go in their sleep. That's the best we can ask for
Hug your grandmother twice. I was blessed with two great grandmother's and two grandmother's and grandfathers. The treats lived till their 90s, the grands all till their 80s. I miss my mom's parents the most. Amazing people that I learned so much from and they are still very influential with who I am today. Give your grandmother a hug for me too.
