Imagine: Harley before seeing you.
"Hi, cupcake!"Harley smiled brightly as the elevator opened in front of you.
You got in beside her and gave her a kiss, she wrapped her arms around you and that's when you noticed the gun in her hand.
"Um, Harley?"You raised an eyebrow.
"What?"
You nodded to the gun.
"Oh right ok. No guns in public."She realised."Oopsie."
