A challenge for you (or anyone interested in taking it up): Once a day, while waiting for public transit, pay attention to the people around you. Does anyone have something interesting about them (hair, clothes, jewelery, weird keychain thing on their phone, etc.)? Ask one identified person about it. See someone who looks like they are on the verge of tears? Ask them “Hey, is everything ok?”

9/10 times you’ll have a brief Q-A-back off interaction, but sometimes it’ll turn into a longer conversation. Yes, it feels awkward. Yes, in some places you’ll come across as rude/uncomfortably weird (keep your dominant culture in mind - you probably wouldn’t try this in some place like Finland or something). But I’ve had some very interesting experiences doing this in the past (usually with the ones who look upset - if you’re willing to be a sympathetic ear you might just make that person’s day).
