Most human beings have gloomy facial expressions when they are surrounded by strangers, be it on a bus or on the street, passing by. Do you ever wonder what your facial expression looks like from aside in such situations? Do you ever look strangers in the eye or smile at them? Why / why not?
Where I come from/live it's just the polite thing to smile at people you walk past or see, on the bus I find it awkward so tend to avoid all eye contact with people and go on my phone or just look down. I do think about what I look like because I don't want people to think "another rude teenager" ect.
