Sorry I'm Late, I Didn't Want to Come

I admit I mostly read this book because the title amused me. An introverted woman spends a year doing extroverted things (talking to strangers, public speaking, improv, throwing dinner parties). Angst and personal growth ensues. This book definitely fits the genre of book that was popular a few years back where writer does weird thing for a year, has personal growth, and writes about it. But it is a cute book and I learned things!
