Her ex-girlfriend.

"What's wrong?" you ask, wondering why Sam freaked when the doorbell rang.

"Hide," she whispers.

"Hide?"

"It's my ex!" she leads you to the tub in the bathroom and pulls the shower curtain. "I'll explain after!"

The doorbell rings again and Sam opens that door.

"Hi, Erin," you hear Sam greet her ex.

"Hey," Erin replies back coldly. "I'm here to get the rest my stuff."

"Right, come on in."

"When did you learn how to make toast?" Erin scoffs bitterly.

"It's not that hard with instructions I found on Google!" Sam jokes but Erin doesn't laugh. "Your boxes are in the bedroom. Do you need a hand with them?"

"Yeah, sure."

You breath a sigh of relief but then remember the waste basket full of used condoms!

"What the fuck is this?!" Erin screams.

"Erin, wait..."

"You didn't wait long for me to move out before you got some cock?"

You hear a slap.

"Erin! Don't..."

"You fucking whore!"

You want to run and stop the fight but you may might it even worse with your sudden appearance.
