Except, you bought it in a rush and accidentally addressed it to your step-mom instead. A little Freudian slip.

A few days later, you stop by step-mom’s on the way home from your trip. You just wanted to say hi. You don’t see her much since that whole affair ended.

You try to explain what happened but step-mom's decided she's not losing you again, and you can’t help but fall right back into her arms…
