Mysteries of New York

I just went over to my favorite greasy spoon in the neighborhood, La Bonbonniere, for some lunch.  Walking down Jane Street, I spotted an Oral-B toothbrush with  small plastic cap around the brush lying right in front of a stoop.  It stuck in my head because I thought the little brush cap was a good way of packing the toothbrush in a Dopp kit without a big bulky plastic holder.

On my way back, I passed the same stoop and the toothbrush was gone...but the plastic cap was still there.

Still trying to wrap my head around that.
