<human>: Can you provide a brief overview of the text?

I'll start. This story didn't actually happen to me, but to my sister. She and her friend were walking around downtown Toronto on labor day, because like all first year university student, they were both bored out of their minds. While walking around they come across a scene that is background worthy so they ask a random guy on the street to take their picture. The man then proceeds to step back twenty feet to 'get' the background, while in the process trying to figure out how to operate the camera. While this is happening, pedestrians are actually stopping to allow this guy to take the picture without getting in it themselves(Only in Canada). By the time the guy actually figures out how to operate the camera, theres a crowd of at least 35 to 40 people held up and watching the photo take place.
<bot>: sister asks stranger to take photo. stranger holds up downtown crowd to take picture of sister with friend, resulting in many stares.
