Come up to a stranger on the streets and tell him something nice, like how his shoes look nice, or he has a nice haircut, or anything . He will never forget you. You will also make his day. After all, unless you are some sort of celebrity or a pretty girl, it’s not every day that you get to be complimented by a stranger.
People going down the street, minding their own business, living in their small world of thoughts, plans, goals, wishes. And then you suddenly knock on their door and say something. It’s very interesting to see people’s reaction their ‘barrier’ being broken and their attempt to something back, or to try to figure out what is happening. You most likely derailed their whole train of thought by simply coming up to them and saying something.
Maybe it’s just me, but I can remember almost all the people who ever asked me for directions, or just approached me to tell me something.
It partially has to do with that the factor of expectation. Nobody expects a stranger to come up to them and talk. Which is kind of sad because it partially alienates our society, making every individual a little bit more isolated.
