I am sure each of us have seen them at least once. I say they are all on a league of their own with their performances. Whether it is a silent act, or a scene stealer. I have a sense of respect for them who have guts, courage and (sometimes) unique talent.
These travellers, backpackers, locals, or whoever they are and wherever they come from, they form part of the street scene which makes walking down the street a bit more interesting. They can be a nuisance to some, but really it is your choice whether you want to stop and see them do their thing. Whatever their reason is for doing this, does not really matter (much).
