You know how there always used to be one kid in school that seemed to know everything about baseball cards. The price of a vintage Babe Ruth rookie card, which cards n a baseball card pack are actually worth something. I was clueless, however, but I really liked the bubble gum. So I bought some packs and slowly built up a collection of random cards that I knew nothing about.
Then one day I hung out with that knowledgeable baseball guy after school and we looked through my collection. Most of the stuff he just flipped through, but a couple cards he put to the side. He then said he'd give me $5 for them. What a great deal, I thought! That would pay for a lot of gum. Obviously I took him up on the offer.
Later I found out that the particular cards he took were worth $100. That was my first introduction to the pitfalls of business if you're an uninformed consumer.
