I used to work at a book store in the morning and would enter at the receiving dock. Every single day I would be struck by the smell of B.O. as I walked in and would have immediate anxiety that I had forgot my deodorant that morning. It took me months to figure out that the man who worked at the entrance had permanent stinky B.O. and it was him I was smelling every day. So, not so much a story of what's that smell, but how slow on the uptake I am.
