I am translating a TED video and I came across this line. Would somebody help me putting this line in simpler expanded form?
"You know, it's remarkable how universal the gesture is of handing your camera to a total stranger"
Since I was asked for edit. All I want to add at this point is I am not totally sure what that line mean. That is the reason I am trying to understand how one can interpret the sentence. Reading all the comments and the answers I now think this sentence has a clear meaning and implications although one can rephrase this in different ways. But the gist or essence of the sentence is simply the same. Thanks everyone for your contribution. Appreciated.
