We all do it, I certainly do.
I sit on a busy train not talking to the person next to me, but why? Conversation enables us to learn, teaches us empathy, opens us up to the lives of others, makes a tedious train journey fly by, boosts our confidence and self-esteem, acts as vital stress relief and a multitude of other things.
There are reasons against it of course - not wanting to annoy the person next to us, not wanting to come across badly, wanting to catch up with the last episode of Downton, wanting to act like everyone else. It's good to take time out on our own to reflect and chill, but sometimes we should just start a conversation and see where it takes us.
Peter Sharp makes absolutely inspirational videos about this and other social topics.
Take a few minutes out to watch his amazing train dance party in Perth. I should imagine this train ride was the best one these people will ever have:
Next time you sit next to someone you think looks interesting and have some spare time, maybe say hello and see where it takes you.
