I have a this problem where I will giggle to much at something like a movie or tv show. I show it to other people and they don't giggle/laugh as much as me. We were watching a movie in school yesterday and I found it funny but I laughed at some jokes that no one else laughed at. Do you think this is just a phase or I just haven't fully gone through puberty yet?
I think it is great when people laugh, who cares if others don't, you are setting an example that you have a sense of humor and a personality, others are probably too scared or embarrassed to be that confident. I would say don't change a thing and who cares if others judge you for it, they are probably going to admire the confidence and sense of humor.
Don't worry about it.. you enjoy life more than other people which is a good thing.
I remember in high school when I had to read a whole page in a book about some pianist. So I kept saying pianist and I would start laughing every 5 seconds.. apparently I was the only one immature enough to relate pianist to penis lol.
It just means you have a really good sense of humor. Some people might get annoyed at how often you laugh or how easily, but forget about them. Life is too short to not laugh and you were blessed with the ability to find the humor in things most people can't.
Laughing is one of the best quality's, my friend (girl), she laughs so much, and after a while of her laughing, we just laugh to the stupidity of it. (Not calling you stupid for laughing).
All in all, it's a good thing. Nothing to worry about.
This is not really a problem. Don't worry about it. You have different sense of humor than others. Besides, laughing is good as said by others above. Besides laughter makes you live longer, seriously.
