I can be a barrier or a passageway, existing exist between what is known and what is new. I wait for courage, or a key. Those who face me must choose whether to stay or step through.

I have no voice, yet I’m full of names. I never move, yet traffic flows on me. I can be long or short, rich or poor, Homes face me, footsteps mark me, and cities are built upon me. What am I?

In the bathroom, I'm a helpful tool, with a funny name that rhymes with bunger. What am I

I decorate , adorn, I’m a source of great pride. From a tree I’m hung with great care and delight.

I make the guard stand in his place, Spur the courier to run his race, The backbone of your backyard’s border, I denote what’s later in the order.
