My girlfriend is just as enthusiastic about my collecting as I am. When I bring the mail in and she spots a bubble envelope/box, she will grab the scissors so that I can open it right then. She even looks at the backs of my T206s. If its a Sweet Caporal or Piedmont back, the next question out of her mouth will be "Doesn't this player have a Polar Bear back?"
At flea markets, if I start digging around at a table, she will scout ahead and alert me to any baseball items that are on other dealer's tables.
If I'm at work, she will send me pictures on my phone and ask me about baseball or sports related items that she has found.
Yeah, she's a keeper!
