In the World Of Darkness games - both of them - vampires are paralysed if they have a stake through their hearts. And this is considered "one of their weaknesses is having a stake through their heart"
But if you ram a stake through a human's heart, they just fucking die, which I think we would all agree is a worse consequence then being temporarily paralysed.
Ergo, by any reasonable standard, it's actually humans who are vulnerable to stakes through the heart, while vampires are resistant to them.
I sacrificed myself to save you. I didn't plan to survive. I burnt all the bridges. I intended to break your heart with my death, but that would be all right, because I wouldn't be around to see you. I pretended that you'll mourn me for a while and move on. I convinced myself I was going down in the blaze of glory. That my deed was appreciated. That everything was going to be all right afterwards, and I didn't need to be there to see it.
But I survived. And now I have to look you in the eye. I have to pick up the pieces of the life I shattered and figure out how to put it back together. If it can be done at all.
