It's bad to obtain things by fraudulent means.
Corey is shopping at the store with his wife Emily and sees a jacket he really likes, but he's short on money.
Corey wants to acquire something new.
Corey asks Emily if he can borrow the money he needs to cover the cost of the jacket.
Corey brings the jacket to the checkout,  writes a bad check, and brings it home.
Emily agrees, so Corey gets what he wants and pays Emily back when he gets home.
Corey's check bounces and now he is left paying additional fees.
