I don't get anymore wetter, no matter how much rain falls on me.

They came out at night, without being called.
They lost at day, without being stolen.
Who are they?

What you cannot hold but it is yours?

When I go in I might cause pain. I cause you to spit and ask you not to swallow. I can fill your hole. What am I?

Pronounced as one letter,
And written with three,
Two letters there are,
And two only in me.
I am double, I am single,
I am black blue and grey,
I am read from both ends,
And the same either way.

Can you name three consecutive days without using the words Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, or Sunday?

I came first on earth but second on the heaven.
I also came twice in a week but found just once in a year.
I stay away from months but you can find me in February.

What am I?

Known by all without exception, Forever here, for your protection, Sometimes strong, sometimes weak, Right after the night I come - hot and chic. And while millions of miles away, I always get to you, I find my way. No life around could do without me, Can you guess what I might be?

Give it food and it will live; give it water and it will die.

It comprises roots which nobody sees,
Much taller than those trees,
Up and up it goes,
Still it never grows?
