You measure my life in hours
I serve you by expiring
I vanish faster when I am thin
and slower when I am thick
The wind is my energy
What am I?

I welcome the day with a show of light, I stealthily came here in the night. I bathe the earthy stuff at dawn, But by noon, alas! I'm gone.

What is full of holes but still holds water?

When it is alive we sing, when it is dead we clap our hands. What is it?

I’m tall when I’m young, and I’m short when I’m old. What am I?

I am written with two letters.
I said with the one.
I usually am seen with the two.

Who am I?

Your mother’s brother’s only brother-in-law is asleep on your couch. Who is asleep on your couch?

Pronounced as 1 letter, And written with 3, 2 letters there are, and 2 only in me. I’m double, I’m single, I’m black blue and grey, I’m read from both ends, and the same either way. What am I?

It's pretty hard to give up.
If you remove a part of it, you will be left with a bit.
Even if you remove another part, the bit still remains.
Remove one more and it still remains.

What is it?

I make a loud sound when I’m changing. When I do change, I get bigger but weigh less. What am I?
