I was waiting in the Starbucks drive thru, and I saw the sweetest exchange. I'm going to give you the details of what I saw and then I'm going to tell you what I think was happening.
First, two young women, probably in their 20s, are standing next to each other in the parking lot. One of them was a policy officer in uniform. They had to be related because they looked almost identical. Their cars were parked next to each other. The police officer opens her drivers door and turns the lights of her cruiser. Immediately, both women start squealing and jumping up and down holding hands while the lights flash.
