Another lost dog boot! A suspenseful tale.

On a freezing winter late afternoon, my guide dog and I were walking home from the bus stop.  Both of us thinking about dinner I'm sure and being inside a warm house.  The boots were all on before exiting the bus.  Since it was only a couple of blocks home and since it was freezing and I didn't want to remove gloves to check dog boots, we carried on.  About half way home, I heard footsteps behind me.  Was someone following me?  They were hurrying at first and then slowed down right behind me.  Should I turn and say something?  Should I go faster?  Was this a criminal going to grab my backpack?  I was tense!  "Excuse me," said a warm kind male voice.  I jumped.  "Excuse me but your dog lost one of her boots.  Here it is."  As he passed me the soggy boot and I thanked him, I reflected on whether or not I had been reading too many mystery books.
