If had one sentence left in the world to say, what would it be?

I would say "I love everyone"

"Don't forget me"

"Keep me in your hearts please"

"Take care of my pets for me"

Or "I want my organs donated"

Or "you better win that soccer game without me"

Or "I'm supposed to bring snack, so fill in for me"

Or "don't forget to eat your veggies"

The movie "a thousand words" is a good one. :)
