I realised recently when we conceptualise and analyse something too much (if at all) it loses its meaning/reason.
However, when I asked myself this question in the past, all I came up with is "it was always going to happen" – and I’m very happy with that answer.
I also answer that way when someone asks about the changes in me- it cuts to the truth and they usually don’t ask any follow up questions
I'm now just sitting back and enjoying the ride
