I shave every day, but my beard stays the same. What am I?

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.

You can win me and lose me but never buy me
You can not eat me and never want to part with me
I can make you cry or bring you joy
I am not a machine and definitely not a toy
You keep me but i am not forever just yours
You might find me in a case or on a shelf next to a vase
I am hard and i am tall if you bump me i am sure to fall
I am made of different materials and am at many events
If your lucky and fight hard I might be yours
What am I ?

The first person saw the bridge step on it and crossed,
the second person saw the bridge did not step on it but crossed,
the third person did not see the bridge did not step on it but crossed.

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?

My thunder comes before lightning.
My lightning comes before my rain.
My rain dries up all the land it touches.

Sometimes dishonest
I can be sweet and also bitter
