If my fiancee did that I would probably lose my mind. I'd want to spend all our savings on a new computer right then and there.
But I actually did this to him when we were still in high school but it was to COD. He'd been waiting forever for it and right after he put it in the XBOX I tripped over a cord and laser burned the disk. He said it was not big deal but the guilt almost killed me.
But then she was giving me a silent treatment, and i was asking was everything ok, she said it is, i asked is she sure, she said - yes, 100%, no big deal, then i said fine, and she called me a dick and i spent night at sofa.
