Me and my then wife were at our local mall. As we were heading to the exit, a younger man, probably early twenties, and a significantly older woman started walking in front of us. Everything seemed normal at first, then they started holding hands and acting very flirty with each other. Obviously, we thought this was strange, but to each their own. They parked near our car in the parking lot so we ended up walking behind them until they got the their vehicle. The man went to one side and opened the back door. The women went to the other side and opened her side back door. They both leaned inside for what could have only been 5 seconds. When they came up, the woman was now a young version of herself. Looked to be early twenties. Mind you, she looked old before. Wrinkles, boney hands, and sun spots. They were all gone. She looked right at us, smiled, and winked. We still have no idea what happened.
