Why Starting a New Job Sucks

I have a new job that I love very much. But sometimes... Change can be hard, people.
  1. Too many new names to learn.
  2. Because things I am normally capable of suddenly have new and unanticipated complexities.
    How do I answer my crazy phone so that I'm on my headset? I haven't the foggiest idea.
  3. A whole new set of office politics.
  4. Having to wear shoes again.
    Ok, so maybe this only applies to those making the transition from working at home to office life, but still. Grrr.
