Whether merely thought or spoken aloud, last words before death are pretty much inevitable.
There’s no point planning them but I wouldn’t be surprised if my last words tended towards these examples:
a) WTF was that all about?
b) Anyway, I love you all.
c) Well maybe not all of you but
d) Never mind.
e) That’s a beautiful cloud structure, I was always good at the clouds.
f) Hehehe.
g) Maybe next time.
