Oh mate, I do the same. I tell her about player X who I am targetting. Or a young player with potential who I sign to a great contract and they immediately start performing. And she laughs.
But like garrett says, at least it keeps us off the streets. They got to appreciate that.
Last night in bed I was playing i OOTP leading 4-1 in the bottom of the 9th and my closer gives up 2 back to back homers to tie the game. I swear, naturally, and my wife looks at me like i'm a weirdo. Imagine if this game had graphical representation as you watched that 2nd homer fly......I'd be 100 times more angry!
