I sit on the crown where the roof meets the sky, A portal of glass looking endlessly high. I gather the sunlight to brighten your room, And swallow the stars as they chase away gloom.

Warning note that this has red herrings. This is where you sleep, You also go here to read. But you can still do anything in this ___

I have wheels. I'm strung out for the kids. I need a very specific environment to mature like a cellar or a cave. I accompany wine for a classic and elegant pairing. And people shout my name when getting their picture taken. What am I?

I have no voice, yet I prevent you from cracking, I have no legs, yet I travel all over your body. The colder it gets, the more you need me, The more you use, the softer you become. What am I?

You can find me in abundance both where water is plentiful and where it is sparse. If you find me in your eye, you'll undoubtedly cry. My descent marks the passage of time. What am I?
