Stupid but hilarious, oh well

New girl left her panties at my place after fucking

This morning I see one on the floor in my room and snap her a picture saying “ I found it “

She snaps me back “ that one is not mine”. Haven’t replied yet

I look around more and yes, this was a regular plates panties that usually has a habit of leaving her bra also.

Well fuck, how should I react to this ? I was looking to add this new girl as a plate but does this change the dynamics

Thanks
