thank you

I was just wondering..

What would a society be without the words "thank you" or any of the other many different words with the same meaning?

Are there any languages on this O so strange planet of ours that don't contain a word for it?

If we didn't have the word, would we not appreciate things? Not show it? Or simply just not have a word for it?

Could it be that if that word wasn't invented it could have had an effect on the human race that made us all grumpy and cruel? Could it mean that there wouldn't be joy in the world?
No birthday parties?
No chocolate pudding?

I'm glad some random person started to use that word..
so to whomever you are..

thank you
