Oh, There's wood there....

This past weekend, my wife comes back from one of those hobby store's that men try to avoid...
She came in with a new candle holder thingy that attaches to the wall.
She proceeds to get out a hammer and nails.
Then she puts the first nail in the wall. All goes as expected.
As she goes to put the second nail in the wall, I hear tap, tap, thud.
Sounding very surprised, she proclaims, "Hey, there's wood there!!".
This struck me as funny, and I asked if she had expected something different... such as styrofoam,....
I was called mean!!!
(This, by the way, was the story referenced earlier this week)
