You were a snarky bastard.

I'm sorry you're gone.

Your memory is, and will be, a blessing.

I didn't appreciate you as you deserved in life. That's generally how that works - time and attention are finite. And each and every one of us could say, truthfully, that we neither gave nor received what we deserved.

Like us all, you were a wonderful and irreplaceable. And as we all will be, you're gone.

I'm a snarky bastard too. If we can't appreciate each other, who will?
