Moment I just had

So my roommate likes to "talk" when I exit the bathroom, which makes it very awkward for me. What does he decide to talk about this time? Apparently there was a homicide on his bus route today. So because I'm uncomfortable what do I instinctively do? I laugh. And he looks at me in horror and says, "It's not funny, it's sad." And I quickly run back into my room.
