I’m tall when I’m young, and I’m short when I’m old. 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.

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

I am 5 letters long.
My first two tell you who I am
My first 3 could be a medicine
My last three reversed could be a young boy.
My 4th, 3rd and 2nd in that order could be a fruit drink.
If you have me you may hang me round your neck
WHAT AM I ?

What is in seasons, seconds, centuries and minutes but not in decades, years or days?

I am not a bull but I have horns.
I am not an ass but I have a pack saddle.
Wherever I go, I leave silver behind me.

Who am I?

Spelt forwards I’m what you do every day, spelled backwards I’m something you hate. What am I?

There's a day, that comes around once a year.
To celebrate the man, you hold dear.
He gave you life, love and will pick you up if you fall.
When it comes to guys like him, He's the best of all.
Who is he?

Who has married many women but was never married?

I have cities, but no houses. I have mountains, but no trees. I have water, but no fish. What am I?
