I one time walked into a bar and took the seat on the other side of the corner from the only guy sitting there.
I told him about my day. He looked angry at me with very large eyes and a big frown. I just continued my story as if nothing happened. He kept the face on for the first 2 minutes of it. I order a beer and one for my friend here. The added rage in his facial expression was hilarious. I continued talking about my day while drinking the beer. He looked at the glass for a few seconds and decided to drink from it.
The new facial expression was tired but slightly impressed by the way I continued to talk to him completely undisturbed.
Eventually, after 3 beers, the story about my day came to visiting a bar with only one other guest who apparently went to a public place expecting not to be talked to.
He laughed really hard. I said, hey, you got to work with what you have.
He then told the story of the very shitty day he was having. I forgot the details but it was truly a shit day.
