It doesnt happen all the time but sometimes i can be doing anything and i get the urge to burst into laughter for no reason, if im on my own i just let the laughter out but i sometimes get odd looks when it happens in public. is it normal?
well.. you're not laughing at nothing... its just that you're sooo not aware of what you're thinking about, that you're not sure or remember what you were laughing at. :).. that used to happen to me.. :P
me:"lmao!!" friend:"what are you lauging at? lol!!" me:"i.... don't know... :S"
Who cares what others think! It makes you feel good, doesn't it? Enjoy it when it happens, it's one of the best things about life, it's seeming capriciousness.
it is normal it happens to me alot even one time i was stinging on stage in a school concert and suddenly i just laughed in a loud voice and i got embraced but lucky my parents was not there
me:"lmao!!"
friend:"what are you lauging at? lol!!"
me:"i.... don't know... :S"
:P:P:P
I agree with Verppisces030990, you just aren't aware of what you are laughing at.
