Both happened at work. First one was a very old, but not quite ratty, cardigan I kept in the office. Second, was again, a very old, knit jacket, again that i kept in the office. At first I thought I had taken them home, but they were both nowhere to be found. I think since they both had labels from a rather nice women's store, someone figured they'd take them.
Neither was particularly valuable, and both were old, but it was weird.
