Is it normal to laugh at sad movies?
Whenever I go to (or see on TV) a sad or romantic movie, I always end up laughing. It drives people around me insane, but it seems the more serious things get (like if someone dies...) the more I laugh about it. I want to change but I just can't. Sometimes the things are so ridiculous that I can't help it, like during really cheesy romantic scenes in, say, the notebook.
Also, I always laugh when batman first speaks in "The Dark Knight" and when Harvey Dent yells "SAY IT!!" in the hospital.
Is this normal?
