Years ago at a job we all had our own toolboxes in the lab, engineers and techs alike. One tech, a nice guy and very capable, had the peculiar misfortune that his steel tools all seemed to be rusty.
Consequently nobody wanted to loan him their tools, only to see them rust up. In some cases, rusting in a fingerprint pattern even. He said it was always like that for him, just something he had to live with.
Imagine having that curse as a gun owner, collector.
