Lately, on my commute through the city, I have started to take my eyes off my book or phone and (dare!) to look up and around and I have realised how those people who I managed to make eye contact with for a split second (or the majority of them) were immediately intimidated, they looked around as if they've done something wrong; until I just smiled at them.... want to know the surprising thing? 90% of them relaxed and smiled back!
