In his defense for smiling a few times during his interview, I admit sometimes I laugh when I found out someone has died or been hurt. I just can't help it. In fact, my manager does it, too. He laughed when he told me the story of how his dad died. I thought it was odd, until I realized I do the same thing. Or even if I'm scolded at work and I should take it seriously, I either laugh in hysterics or cry in hysterics. Both are just as embarrassing. It's not because I think death is funny, it's just a nervous thing or something.
