I am a boundary with no wall, A door with no hinges, A keeper of light and secrets. When I part, another world appears.

Always hungry for the trees, X marks the spot where branches fall. Ending forests with a breeze, For each chop from these

I hold coffee, wear a grin, or take your wallet on a whim.

Improving the look atop a pie. Or outside the window of a maiden to climb. My woven arms support all charms. In diamonds my carbon can be formed in a... What am I?

I can strike at any time, there is no reason or rhyme. A shock to the system, but you'll be fine, your brain will thank you, in due time. If my purpose remains unclear, I'm what writer's block doth fear.
