The collectible bug

I think I've been bitten by some kind of bug. A collectible bug, I guess. Whatever happened, I've become obsessed with Paddington Bear. I'm spending WAY too much time and money on eBay collecting bears. I spend my weekends dragging the family to garage sales looking for Paddington stuff. I've read almost nothing but Paddington Bear books for the last six months. Am I mad? Do I have OCD? Or is this just what it means to be a collector?
