My wife knows only too well about the telescopes and the antique firearms - they were there when we got married, they will always be there (though continually change
)
There is only one kickback to my hobbies - my wife and kids do NOT buy me presents for birthdays, Christmas or Father's Day - I told them LONG ago that I have enough stuff and enough funds tied up into them to last me a lifetime. It's a fair trade off, and one that I instigated.
