<human>: Can you condense the text into a few key points?

This happened when I was around 17. 

**A bit of backstory**:  

My mom has a pretty fun sense of humor, and was always very nice about driving my friends and I around before any of us had a car; she would drop us off at the mall, movies, whatever. She also had zero problem fucking with my closer friends as she would with me. Sometimes,  after loading up the car with groceries or leaving a restaurant or something my mother would get in the car and start driving away, and I would have to catch up, open the door and get in. Perhaps not the best of parenting, but I had fun and it was an odd bonding thing. 

**Cue the event in question:**

 My family, being my mom and two brothers, and my best friend still to this day, are getting ready to head home after a long day at the Evergreen State Fair. I lag behind a bit to relieve myself and my friend hangs back with me. I finish, and we head out to the car. As we walk through the gravel parking lot we see my family's van driving away. We smirk to each other, being used to this, and we give chase, running after the van until we catch up to it on either side, open the sliding doors, jump in and close the doors.  It was around this moment when I realized I was sitting down next to toddler's car seat, and both of my brothers were teenagers... *This was not my mom's van!* This was some poor young couple's van with their toddlers in the back seat. My friend and I look at each other, eyes wide as can be, and as the poor woman starts to scream bloody murder we leap out of the car and run as fast as I can remember running back through the parking lot to try to find my family.

Perhaps worth mentioning is that my friend and I were wearing ripped jeans, black band t-shirts, chain wallets, and long hair. I'm sure we looked a lot like people trying to rob or kidnap someone to the poor lady.
<bot>: my mom makes me chase the family car, I did ang got in the wrong car, scaring a woman to death.
