I think I'm finally breaking my wife down..
The other night, the kids and I were talking about getting rid of our air hockey table (AKA big table for storing junk) to make room for a few more video games... Even though the table doesn't get used, she doesn't want to let it go just yet. Then she says, "Maybe you should just convert the F%*@ing garage into a game room!"
I have 4 games and a pin downstairs now, and 2 more sitting in the garage waiting for time and space... I haven't pushed the issue yet, but I'll just keep dropping small hints until its her decision
