One day we visited my grandparents cemetery,my boy started crying, and asked me why my grandparents are buried here while I said people went to heaven when they are dead. I had to say that our body remains here, but our soul/spirit go to heaven and we live there.
Then one night he tears again, then cry, when I ask, he said if it's just spirits/souls go to heaven, we won't even have a face there, our family will never be able to recognize each other, and we won't be able to re-unite in heaven.
I almost cried myself.
