My wife is supportive of the playing, though certainly wants me to spend more time with her (ok, were newlyweds, less than a year still)..
She appreciates the buying and collecting.. to a point.. I admit to having way more than "necessary".. Ive been doing that for 30 years though..
And I do try to use the method mentioned below.. if one comes in, one will usuaully have to go out at this point..
We just agreed to remove the actual bed from our guest bedroom, and utilize the space to share it for both my guitars, and her photography stuff.. Seemed a great idea, as we have guests in there 1% of the time, and can easily get an inflatable air mattress for when we do!
