OM Gosh. I can relate to this.

I wear spectacles for driving, and I had to stop at a public toilet one day. Somehow I dropped my spectacles in the basin. Don't ask me how I did it because I can't remember, but I do remember how disgusting I felt having to fish them out of the toilet, and put them back on after I'd washed them over and over again. I had to put them back on or I'd not have been able to drive away.

That has to be the most disgusting thing I can ever remember happening top me that was totally my fault. I still think about it and cringe.
