Use the same all purpose explanation similar to when she finds the new motorbike you had not told her about. " It followed me home !!!" .
I thought this was the all purpose explanation [youtube]http://www.youtube.com/watch?v=2g5Hz17C4is[/youtube]
I have gone thru most of the scenarios cited in this post.My wife went thru good idea honey phase to when do we sell.Now her only comment is you bought more coins didnt ya.Still she hasnt left me yet so I guess I'm ahead of the game.
Maybe it's just me, but life seems a bit more simple now that I am alone. I do have to wash dishes and cook, but that's why I have a microwave and dishwasher. Looking at prices, I think I need to buy more silver really quick, and it feels good to be able to.
The storey of every dude who has bikes, boats, guns, a stash etc. His biggest fear is she will sell it for what he told her he paid.
