Lucas was asking about heaven and when he was going to heaven...
Kyle told him that science says that he has about 70 years on average.
That's my husband. It probably totally confused Lucas so he dropped it.
So Kyle told me that Lucas was asking if he was going to heaven a bunch.. He would ask if he was going in 15 minutes, next week, tomorrow.... Kyle kept telling him no 70 years or a real long long time.
