As we age we become more social, don’t we? Strike up a conversation with anyone anywhere because why not? (the photo of the taxi driver is because I just got out of a taxi and met a new friend!) You meet a lot of people that way. God how my mother embarrassed me when she did this when I was a teenager.
We have a curiosity (at least I do) to find out about people. Where they are from, what they do, if they have children, etc. – looking for a commonality. I think we all want a tie that connects us.
Think about it. We all want to belong.
