Some people do know how to laugh it out their own way.
Take my friend M. Between his bushy beard and mountainous moustache, we can hardly make out whether he is laughing or crying after hearing our joke.
CM is a different type. You utter a comic story and he will LOL so much that the building will shake.
Female friends have a special knack. S will run for her kerchief, close her mouth and blink. Soon there will be tear drops in her eyes, leaving us worried whether our joke made her cry.
M is funny. Only his teeth will protrude. He will come close to you and make a sound like a mouse screeching apukukuk…
As someone said, the next time you see anyone without a smile, give one of yours. Let them smile or laugh the way they choose.
