Some hilarious "revelations" here......what a great forum.
My wife and I have three bank accounts, joint, hers and mine. I don't know,(or care) how much money she has and she doesn't care how much I have. We discuss all joint purchases and also any significant personal purchases before buying, just to be open and honest with each other. I keep a gun inventory and she knows where it is, so if she is interested she could always look.
She isn't into hunting or target shooting or plinking - her interest in guns is only self-defense. She has a 9mm S&W semi-auto, and a replacement (Stoeger 800) is on order for her carry pistol. She knows how to shoot the bedside S&W 586, and the Mossberg pump that lives in the corner. I always show her any new gun purchase, and she expresses "appropriate interest" but clearly isn't enthused with old C&R milsurps and is only moderately interested in the rest.
