Talking to Your (15-Year-Old) Self

Every Friday, I post a series of unrelated questions meant to spark conversation in the comments. Answer one, answer all, respond to someone else's reply, whatever you want. Very casual. On to this week's topics of discussion...
1. If you went back in time and had lunch with your 15-year-old self, what about your current life would be most surprising to the younger you? Also: Where would you eat?
2. If I ever have a big public meltdown, odds are it'll happen in a grocery store. I'm usually laid back to a fault, but when people block entire aisles with shopping carts parked inexplicably sideways, my inner Michael Douglas-in-Falling Down gets dangerously close to taking over. What really-not-that-big-a-deal behavior drives you absolutely crazy?
3. To balance out the responses to the previous question, let's add a little positivity to the world. Tell us about the last time someone did something unexpectedly nice for you.
4. I was telling a co-worker this week about one of my dream jobs: coming up with ideas for documentaries. I have no relevant film-making skills for any other portion of the process, nor do I have the cash to fund such projects. But that's what makes it a dream job, I guess. Let's pretend you have my dream job. What's one documentary you'd love to see made?
Have a great weekend!
