God has entrusted things to us and I can't think of anything more important than people...especially the people in our families like children. I know mistakes happen, but seriously, a child left in the back seat of a car is quite a bit different than saying, "Honey, sorry I forgot the get the ice cream out of the car and it melted."
Where is our sensibility and sense of responsibility? It's a child! It's a human being! We are responsible for their lives. Their lives depend upon us! I'm sorry for the father and yes, he can be forgiven, but really bad choices have really bad consequences and now he's going to have to live it. No excuse whatsoever. I'm thankful for God's grace but there is no excuse whatsoever for this type of completely irresponsible behavior. I'm saddened and upset at the same time.
