They shiver right before dying and there is no way you can stop them from doing it. Neither shiver, nor die.
You can hold their hands and try not to cry. Not yet, not in front of them. It can wait a bit more, the crying, you have all the rest of your life to mourn them.
My dad has just become an orphan and it breaks my heart to see him cry. His eyes are cerulean and they are way too beautiful to be drown in sadness.
Bye bye Nana, your lasagna will always be the best ever.
