Bestie Parks Her Car At My House On The Weekends

Leo and Rebecca BUZZ QUESTION. One of my girls has asked me if she can PARK her car at my house for the last 2 weekends! Didn't think much about it but my HUSBAND say's she's CREEPIN and that's why she's wanting to leave her car at our house for the weekend. She has told me it's because she is leaving town. My husband has asked me to tell her NO MORE! What's happening here?
