My wife understands me perfectly, she tells me regularly by sighing loudly and saying "geek"...
my wife is nothing but tolerant, but then she knew about my GW obsession before we got married and even tried to paint some items which some girlfriends do and you know you have to correct them because lets face it there are NO goblins running around with pink robes with yellow trim...
then later she wore the same expression when i was collecting airsoft kit and more jackets/combats/webbing then an entire battalion of infantry.
now i do bushcraft, volunteer and attend outdoor training courses, she's even up for coming out walking with me and i've managed to keep her in reasonable comfort whilst at a festival (camping).
when a new jacket or crafty item arrives her response is usually "not another (insert item here)" and my response is generally "What were those shoes/makeup/top/jeans/jacket you bought the other day?"
so yeah she understands me, but i like to rub it in
SWMBO "you can go off people you know"
me: "you can go off me but you'll never get rid of me"
SWMBO "Why did i marry you again"
Me: "Didn't i trick you into it and you didn't realise until it was too late

"
etc etc
