I'm so sorry for the loss of your dad.
The first major shift I can remember having in perception is the day my son was born. When they placed him in my arms everything changed and looked different to me.
The next major time was when we lost my kids dad to cancer.
Our experiences really do shape us into who we are and how we see the world.
Thank you :-) It's a bit like opening your eyes to see things in ways you never witnessed before. Nothing is the same after that, we adapt and evolve into our new form so to speak. Becoming what our experiences have revealed.
