I can't precisely remember the last time but every now and then you have a short conversation with a stranger whom you know you'll never meet again. Each time this happens it makes me feel happy, it brightens my day a bit. However, it also makes me think about how rarely this happens in the real world even though we are virtually connected to almost everyone.
It reminds me of a short poem by Walt Whitman:
Stranger, if you passing meet me and desire to speak to
me, why should you not speak to me?
And why should I not speak to you?
