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

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

You see me once in June, twice in November, and not at all in May. What am I?

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

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

Take one out and scratch my head, I am now black but once was red. What am I?

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 am the largest in my family of fifty.
The youngest of our family lives separately from the rest of the family and so do I.
I am regarded as harsh and tough.
I am so large, you cut me in two equal halves,
each half would still be larger than the second largest member of the family.
Who am I?

I am green and found in the forest and have needles instead of leaves. What am I?
Hint 1: It can be used for Christmas decorations.
Hint 2: I have a strong, scent that is used in air fresheners.

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.
