He didn't miss a step and strode on to the escalator.
She was air kissing a friend hello as she gave a wink and waved another goodbye. He didn't know if they were friends or colleagues or acquaintances? She had this outward consistency with people. The smile similar in every case. The message sincere, all the way up to her eyes. He never knew how she had the energy to give that to every person she came across. He did too but he kept the number of people much lower. Much much lower.
Before he was half way down the escalator, she had twirled around on those ridiculously high heels and was headed for the exit. There was a bounce in her step. He remembered that playful gait that always resulted in her bumping against him as she talked without a breath about many things, when they went for walks. He knew when she was happy. She was right now.
There was a day more than a year ago when he saw a her walking in the distance and he pulled up next to her in her stiletto over the knee boots and said "nice shoes" in his most casual voice. She didn't smile but said "hello" that time. He wondered what she would say this time. Much more had passed under the bridge since then. He left her. She had tried to convince him to stay but he left her anyway.
As he reached the bottom of the escalator and stepped off, he watched her happily skip away.
