"Snuggle", this cracking me up. I'm glad you brought this up cause I too have done this numerous times. I ran over a very loved family dog and found myself laughing as I hammered the cross I made and even etched on. Instead of crying I just hammered and laughed saying I love you "Levi", I'm sorry you ran under my car and I didn't stop. Or my ONLY grandma's funeral when I found myself not being able to stop laughing and having to leave the palor. Or when my car broke down for the hundreth time and I had to walk about 10 miles home in the middle of the night laughing. Or the accident that happened the other day on the interstate and they had a sheet thrown over some dead person.
I watched the movie "Dictator" the other night, and as inappropriate as it is I laughed my butt off. I think that is one place that influences us to laugh in these situations. TV sheds humor on the worst of things. Just watch "Family Guy" sometimes. I don't know if it is something we should cure because what's the other option.....crying ourselves into depression?
