I can hear that voice. It's very clear. It's a bit of a mocking tone, saying 'Duh, Jordie, don't do that! It'll ruin your chances of living happily and innocently afterwards!'
I don't block it out. I don't ignore it or anything. It's just that sometimes, where there's a will there's a way, even if that means hitting the sane and logical voice in the head and going 'Duh, Little Voice, you can do this and not die!'
'Duh, Little Voice, you can cut slippery kaffir lime leaves with a sharp knife and not stab yourself!'
and, my favourite,
'Duh, Little Voice, you can pour hot caramel onto a balloon!'
Moral of the lesson: Don't. Be. Stupid.
