Wow, that's a pretty adult thing to know about at age 13. I don't know what I was doing at 13, but it sure wasn't looking up savings plans.
I went with my brother to an amusement park today and I was in charge of the older, 10-14ish old niece and nephew. I peeked at my phone in line and my niece asks "what kind of phone do you have?" I say "Nexus 5"...and she replies "Yeah my mom and dad have that...I just have a Nexus 4. I'm so poor." I asked why having a Nexus 4 makes you "poor," and she said that if you didn't have the latest "thing," then you're obviously poor because everybody wants it, but you obviously can't afford it.
We got into a little conversation about how people who don't always have the newest thing, actually are the richer ones, by simply saying that "Those people still have the money that other people spent on a phone" and we joked about how you couldn't possibly go from "cool with the latest phone" to "loser with an old model" in one day, when a new model is released.
Here's hoping something stuck in their head :)
