Type a message, and the ReubenBot will reply. Type 'exit' to close the program.
You: I feel like in this modern era I have become more detached from my fellow human beings. I take the underground every day and I see thousands of faces. I assume they're all real people with real thoughts just like me but there's no way I can ever be sure. If I were to ask them a question of any significance I am sure I would be looked at like a complete idiot or worse still a madman. Perhaps public transportation isn't a good venue for social interaction what with the noise and the heat and so on but I'm sure everyone else in the carriage feels as alone as I do.
Reuben: interaction
