A while ago:
I was riding on a bus at night. The bus was mostly empty, and I thought, "Right now I don't need any company. My reflection is sitting right here beside me in the window; he's all the company I need." I leaned my head against the window so that our two heads met.
I looked across the aisle and noticed my reflection in the other window had no one to keep him company. There were three of us, after all, and he was also leaning his head against the window, expecting someone to meet him there.
