Man am I lucky that my wife never gets on my case about my hobby stuff. I don't get on her case about her purchases either, we both work hard for our money.
I went to the hobby store today as my wife got a kids name off the Angel Tree at her work. The kid is into WWII and wants models.... needless to say I volunteered to do the shopping for that one. I got the kid a Flying Tiger P-40, a 1/48 Pershing, paints, glue and brushes. Fun stuff.
