What time is it when you see cows sleeping in a field?

If you take off my first letter I am a pronoun for a guy. If you take off both first and last I am a short way to say hello. My first letter is the fourth from the end of the access. I am a flight of fancy!

I am always above you, but never in the sky. I can be decorated, but have no face. I hold up the roof, but have no hands. What am I?

I’m a frozen moment in plain sight, within a frame that holds it tight.

You can fiddle it, it's not a device. Bent or straight, it depends how you hold it. Don't fiddle in public, it's impolite. As you grow you stop sucking on it.
