Season 5, Episode 10: Too Old for This

You're invited out. You politely decline, and suddenly, you're a horrible person. Our first letter discusses what to do with the frustration that comes from…well…other people being jerks. But the second is from a thoughtful friend, wondering how to stop her close, loving pal from always offering a solution that's worked for someone else. Plus, Joss's foray with a personal trainer and the shocking amount of sweat she can produce.
