Maybe she's more worried about her vibrator running outta juice,
Specializt. There are people like that. A friend won $10,000 in a local lottery 20 years ago. He gets home, scratches off a few tickets while his dinner's cooking. Sees he wins 10k but is too hungry to celebrate cuz it's his favorite dinner. So he eats dinner, rechecks ticket and realizes it's REALLY $10,000 and then decided it was time to get his dream truck build started (which is done). Also, the dude might be a joker so his wife could think he's trying to pull a prank on her and takes it with a grain of salt.
