Maybe my way of thinking is because we have a day along the year to do the same you described.
It’s a personal thing. I’m not criticising it. Only I saw in the News how in the States there are gatherings of people attending to meetings to celebrate lives of people who recently died.
I could’t do it. I need more time. I attended to my father funeral and it was a nightmare for me. I still couldn’t remember positive things because I was not ready. I only felt sadness for the loss and needed to be alone.
