Wow, so scary. My sister almost had something happen to her once, too. She was about 4-5 years old and had a tendency to wander off. She would open the front door and just slip out -- we had to watch her like a hawk. One day, she wandered off and someone pulled up and told her to get in the car, saying she was her grandma. She got out of there, or someone stopped it -- I don't remember which -- but it was very scary.

You tell this story very well, vividly, and I'm glad you are safe and able to share it.
