Shoelaces, again

I thought I had the shoelace problem under control, but obviously I need to go back and spend some more time here. This was witnessed today as I was at the grocery store on this bright, cold morning. A heavily bearded gentleman in the checkout line one register over from me called over as I bent down to tie my shoe, yet again. "You need to double tie those!" he said with a smile, "That's the third time I've seen you bend down to tie them in here." I smiled and shook my head and said, "I know. They're always untied." Then I laughed in the car all the way home.
