I wander far on wings of mail, a lightweight traveler, thin and frail. Stamped with care, no wrapper's hide, just ink and views from lands I've spied. From beach or peak, a memory's trace, greetings short in a pictured space. No box confines my brief delight, connecting hearts through day and night.

I’m tall in the sun but hide in the shade, I mimic your moves, though I’m perfectly made. I have no features, no eyes, and no mouth, Yet I follow you North, West, East, and South. I’m as dark as the night and thin as a line, Attached to your feet, but never quite mine. What am I?

I am a protector who sits on a bridge. Only one person can see through me, while others cannot. What am I?

Powered by the swirling air, my arms spin slowly upon my face. Their motion makes my gut churn, And in turn, people use that to crush.

A pool of black, for writer or hack, To pour their imagination. Without a feather, to draw me fourth, I stay stoppered in stagnation.
