I can mean to lose energy and droop when exhausted, or to signal down a yellow taxi on a busy street, but on the 4th of July, I wave proudly from a high pole. What am I?

I can unlock antique doors without a notch, staff a vessel with a bare minimum crew, and conceal dark family secrets inside a bedroom closet. Strip away my flesh on Halloween night and what am I?

I am colorful when packed together, but invisible when scattered. I rain down when the new year begins. What am I?

What kind of musical note goes up when you take it off?

Why did the tiny acorn blush when the squirrel complimented its autumn cap?

I travel to your Thanksgiving feast in a special boat that has no sails, oars, or motor, waiting to be ladled over warm turkey slices and mashed potatoes. What am I?

I walk on one sharp point while holding a pencil in my other leg, spinning around in geometry class to make perfect circles. What am I?
