Mine used to give me a hard time about the amount of time I spent on it how it seemed like an obsession.
Then I told her "Hey look, a guy needs to have a hobby to keep him sane. Look at Tiger Woods, now his hobby is a lot more expensive and a lot more obsessive. Is mine so bad?"
To which she responded "You have a point! Go play with your Jets. I'm going to buy a new pair of shoes."
She has been a lot more understanding ever since
