It supposed to be something spontaneous.
But I found how I can't do it spontaneously.
And laugh only if I let it out.
is it weird? You found something funny, and you actually CAN LAUGH to it, but... you DECIDED to hold your laugh and just smile.
Well, I think I have to stop doing something like that. And after I let my laugh out (instead of hold it and just smile) for something funny, I feel very relieve.
Feel how wonderful it is to let your laugh out.
look which one is better :)
