I Laugh At Things I Should Not Be Laughing At

So my Father's going through some sort of depressed phase as he approaches 60. And my mother sat me down to have a conversation about it, she mentioned that she suggested for him to travel to his hometown where his family is. But he said he couldn't. She said "Why?", and he exclaims [b]"Because everyone's dead!!"[/b] and at that point I'm laughing so hard tears are streaming down my face, and I knew she was serious but that made it even funnier so I laughed even harder and fell out my chair. It's so dramatic, it's hilarious. I'm still laughing. I don't think I've ever laughed so much in my life.
