Is it alright to start laughing for no reason?

Ok, i was at the shops today getting some groceries and then out of the middle of no-where i start bursting out laughing, then i feel on the ground laughing for literally 5 minutes, i don't know if this happens to anyone??? but i was laughing, then some people just looked at me and snobbed me off and i heard them whispering "what a gay freak" i mean, i don't know what came over me but if i saw someone at the shops laughing on the ground i wouldn't care i would just keep getting my groceries, i wouldn't even look, but the weird thing was i don't know why i was laughing, i mean it was just laughing like a baby and laughing like i have never laughed before, it was totally strange!!! it's never happened to me before, but laughing for no reason at the shops, is weird, i mean it was fake laughing pretending to laugh, it was actually full-on the ground laughing, but the good thing is at least i know now that i have proberly officially cured cancer from myself and if i ever get it, i will just start laughing at the shops and it will cure it!!!

Its also very good to start laughing because, it makes you feel better and it makes you live longer, laughing cures cancer and its just great to do, even finding something for 5 mintutes a day to laugh about is funny and will make you feel a lot better and for some reason even when i am on the computer i am always smiling and it makes me feel good!!!

I smile at everyone and for some reason i will just go up to random people and have a conversation with them, i am good with that, ill be like, so how are you, whats your name, even if i don't know them!!!

well where get along like a house on fire then, i really still don't get that phrase!!!

as long as you had fun!

OMG! and i thought I was the only one that sudden laughter just hits, thank god it does not come very often!
