Toronto police officer Mark Borsboom is famous on the Internet. A photo of him has been posted and shared on the Internet by many people.

The photo shows the officer is doing a simple, good thing—tying the shoelace ( 鞋带 ) of an old man.

Mark was on duty, helping cars leave the parking lot. As he was standing near the exit, an old man came near him. The man had no feeling in his hands because of a health problem. The old man had a long way to walk to meet his son, and his shoe had become loose ( 松的 ).

He asked Mark if he would mind tying his shoelace for him. “ I didn’t think anything of it—I said ‘sure’ and tied his shoelace. I didn’t know someone had photographed it. ”

The photographer was Jason Cassidy who happened to be passing by when he saw the act of kindness. Jason posted the photo on the Internet and it quickly became popular.

In fact, Mark has done many more interesting and dangerous things for his work. His normal job is catching criminals. On one hot day he spent hours sweating in a van ( 在小货车里淌汗 ). He described the task as “ a million times harder ( than helping someone to tie his shoelace ). ”
