Describe what your OCs phone would be like, in however much detail you desire.
A rotary phone. Deepest black. Inlaid with gold.
The numbers are indecipherable. The letters are a script unknown to mortal eyes but keenly known by the soul. The dial tone pierces the deepest recesses of your mind. You don't remember dialing. You don't remember the conversation. You don't remember hanging up. Something is different now. You aren't sure what, but it feels Right. You Can't feel unsettled by it. You want to. God you want to. But you Know your life is better now. You Know your life will never return to the way it was.
You want to use The Phone again.
