Images at the Playground

It has become my daily routine to take a walk in the afternoon to the nearby park before anything is done with my stenosis.  As usual, there weren't many people on weekdays at the park except two places, that is, the dog lovers' area and the playground. I had enough energy to limp around the lawn. After that, I stopped at the playground. There were some parents with their children playing there. The following are three sketches I did at the playground.
