This was taken a few weeks ago in the St. Lawrence Market, the wonderful fresh food market here in Toronto.
I often go there because on Saturdays it is a sea of humanity and a target rich photo environment.
I noticed the father showing his young son the live Lobsters which brought back old memories of my father doing the same thing with me when I was about the same age as the boy.
And I grabbed this shot.
