I don't think I'd like any last words, to be honest. I'd want to die quietly, because by the time I was about to die, I would've wanted to say everything I had to say to everyone. Everyday, I tell the people I love that I love them. To make sure that they know. In case they die or I die. Silence would just say everything, in my opinion. Instead, I'd just give them a look. A smile. That's it, a smile. Then I would die. Because I think a smile is more poignant and significant than anything words can say.
But if I was just suddenly killed before I got to say everything I wanted to say, all I would say is: "Thank you..." I want everyone to know how grateful I am.
