I go by myself. The voices in my head give me plenty of company. Plus, I'm not sure which on of my friends is really a government spy. I don't like people spying on me and stealing my ideas. I think the government has beams they can point at your head and tell what you're thinking. They could easily disguise one as a tip-up, and you'd never know.
If going by yourself sounds too lonely, try singing to yourself out loud. My new favorite is this
Bill Murray Star Wars Song. You can write your own verses about your favorite Star Wars characters. It's really fun when you're out by yourself. People might try to mess it up and put in Star Trek stuff. That's wrong!
Did I mention I don't like people watching me eat? I also hate scratchy forks when other people eat.
