I was taking an Uber from Sonoma back to the Bay, and the driver was one of those people. He wouldn't stop talking about how he was spending thousands a month on rare cards, then reselling them, all the while losing money, his wife, etc.
Fortunately it was the latter for me. I'd love to keep buying the stuff but it's such a waste. Better to buy singles I actually want. It's just not as fun as me being the one who pulled the card.
