I have a male friend who never takes things seriously until he's performed an action with a disastrous result, forcing me to scream at him. Nice guy, but no matter how much I say, "DON'T," he almost always will. T_T
So the one night, I had set out all of my make-up for some pictures I wanted to take the next day, including my MAC Rule shadow, which I depend on for my undereye circles. I specifically told him to be careful around the sink, because I had a bunch of make-up set up around it. He went to use the bathroom (which is in the very back of my apartment) and didn't come out for a while...and when he DID come out, he had "painted" his face with my make-up, thinking it was funny. Of course, he knows shit all about make-up, so he had dipped his dripping wet fingers in to just about everything, including my MAC Rule shadow, ruining them.
I swear to God, I almost ripped his head off. He was nearly in tears by the time I had finished calculating how much he owed me to pay for it all--it was well over $100. Lucky for him, I only had two MAC items out, and he had left the concealer alone.
Another time was all my clumsy fault. I had just bought Electric Eel eyeshadow. I opened it and set it on the edge of my sink, then turned around to rub my hands on a towel. When I turned back around, I accidentally knocked the eyeshadow in to the sink, breaking it all up. D: I only had, like, a quarter of the eyeshadow left in the pan when I'd finished salvaging it.
