My Grandmother just died and my mom wants me to say something to my dad! What should I say?

You: Hi dad
Dad: Hey
You: I'm really sorry about grandma
Dad: Itz ok
You: You know dad grandma might not be here but she's somewhere where it counts (point to your heart)  here (smile) I love you dad (give him a kiss on his cheek)
Dad: I love you too kiddo

Hope it works and I'm really sorry about your grandmother

:)
