She's on to me

I got home from work today and my wife said "do we have new speakers or something?" "What do you mean?", I say. "Well, the stereo has been on all day and you don't usually leave it on, unless there's a reason." "No we don't have new speakers! Do they look new? I just forgot to turn it off before I left for work". However, I said nothing about the pre-amp I just bought or the cables that I was burning in. ; )

She's getting smart.
