I used to when I was younger. When I realized I had a goofy laugh, I had to train myself to laugh differently.
When I got to college, I met a girl in some of my classes with a loud, donkey laugh, and it startled everyone the first few times they heard it. But she never acted self conscious about it, and she was such a sweet, likable person, that her laugh became endearing to everyone. Good for her!
I don't know what my laugh is. I just know that if I start laughing too much, then I might end up silently laughing, and look like i'm changing into a vampire or something (red face and extremely visible veins.) or that's what I've been told w)
