Do you ever think about friends and relatives who passed away?

Sorry did not know how phrase the question properly. For example, if there is a Heaven. Do you wonder what they are doing? or what they are seeing? Were they reborn into another life? or are they just in a state of oblivion. I’ve been thinking about friends & family who passed away recently. Whenever I think about them I am like wow they are really gone. Then you think about all the times spent together. It makes you want to get closer with the family and friends that are still living. These days you never know. We live in a crazy world where anything can happen. I really hope there is an afterlife. So many people I want to see again. Life is so crazy. I guess what I am saying is we should cherish and love one another. I have a friend I have not spoken to in a while. We knew each other most our life. We got into an argument while playing basketball and stopped speaking to each other. He stopped speaking to me so I stopped speaking to him. I really want to apologize, but we I don’t know. It hurts are parents that we stopped speaking to each other. I don’t know hopefully one day I get the courage to apologize and swallow my pride. I guess this story I shared contradicts what I wrote earlier.
