I find it kinda weird when people said I or someone else laugh too much, or when people said "its not that funny, why did you laugh that much?"
I believe when God created the ability to laugh for human He never set the limit on how much you can laugh even when you laugh until your tummy hurts you can still go on. But of course yeah when terrible things happen its quite improper to laugh, but basically you can never over-laugh at something that funny. Remember that laughing makes you healthier and keeps you young.
So keep laughing my friend! And don't tell us that we laugh too much!
