Oil & Bearings

This one is really bizarre, but I have to share it with you all.

For the first few weeks of living here I would get random sniffs of oil or some kind of industrial oil smell, but it didn't end there, something really odd was the simple fact I would also find very small ball bearings on the floor in the hall way or in the carpet. I actually thought that maybe the vacuum cleaner was begging to pack up ? or that some of the furniture I had moved in was falling apart. But these bearings were really small, I think in all I found about 7 of them, sadly all of which I threw in the bin. At the time I thought nothing more of it, so it didn't bother me. It's only when I look back it seems to add to the bigger picture.
