'Why no honey, I borrowed this from ....' Make sure it's somebody she doesn't like or that she knows the borrowee's wife.

'Honey, you know this is a good investment - it will still be worth $$$ in a few years.' Up to you if you mention how the shoes, purses, china aren't worth squat in 6 months.

Start a lend/lease program with people you trust - rotating gear will become a blur. Also resist showing or watching gear vids - keep the gear spotting knowledge low.

Get her started in her own passion - I got my [now ex] wife back into collecting Barbie's. She wanted a doll house and I leveraged a 3HP tablesaw [still have it] out of the deal. Caution - this approach can get out of hand.

Don't listen to the 'why hide it?' guys - they are married to a testosterone poisoned woman.

This is the one area for having all BLACK colored and similar sized gear - 'Why no honey, I've had this a long time.' Just don't stack it all in one pile.*** Full disclaimer *** I've been divorced for 9 years and happily single. I had a long time rifle competition, wood and metal machine tool, train and guitar habit whilst married.Russ
