Greetings.

I wonder why do people greet you "happy birthday"?
or "happy valentines day"?
or "happy new year"?
or "merry christmas"?
or "happy easter"?
or "selamat aidil fitri"?
or "have a nice day"?
or "thank you"?
or even "good night"?
and those greetings are able to put smiles on your face..

Well, from what I think, it's a kind of appreciation to the one you greet. It also means that you don't forget the one you greet, either as your relatives, friends, or your mate.

I thank everyone who appreciates me through their greetings. Anyway, happy white day everybody. =)
