Fuck you for wasting all of the material I was using to do my research with. You realise that was the only bottle of this material on the whole damned planet and that it was therefore priceless?
I told you that I was using it for my research and that you could use a bit, but to be careful because it's the only bottle of this material in existence and that there will be no more of it ever once it's gone.
I didn't say: here, use it all up for your worthless project!
You think I can find something similar that will work? Well, I just tried 'something similar'. It doesn't fucking work. Because it's not the same. The electron and hole mobilities are different, the recombination zone forms in a very different location, the material has different electroluminescent properties...
URGH.
(there's no science tag?!)
