Have you ever wondered why we meet the people we meet? Are we all wandering in space and somehow we collide with each other just like the extraterrestrial objects? Is there a reason why people meet?
It’s that magnetism one rarely feels towards another human being. Here I am not talking about love because I would probably never understand that feeling and I have decided to leave it alone, at least for a while. I am talking about total strangers, the ones you see and instantly you feel very fond of them. Then they leave just as easily as, well you can’t say "met you" for you really didn't meet. You have hardly spoken to them. You never really looked in the eyes. But somehow you felt connected to them.
I read an article on TOI that said that probably such fond strangers are your dear ones from another life. How would you ever know? Probably some things are best when left alone.
Most of the times what remains of any relationship is the memory of the departure. But with this fond stranger, the only memory is of meeting him/her, not of going away. That's why, it forms the fondest of memories, they remain the fondest of people.
