CLOUD 9

I am in cloud 9, to see the comments about my blog.
I am very much motivated.

By the way, what is this "In Cloud 9".
I did not know what it means, until I read "Hai Madan" in last weeks AV.
Generally the clouds can be at a maximum height of 8 miles. So when we want to express some high, happy feeling, we say, I am in cloud 9, like beyond the possible height of clouds.
Americans introduced this word to English in 1965.

I liked this, and hence this info sharing.
Could be a repeat for some of you though.
