Reckless Driving

Yesterday me and my parents went all the way by New York to pick up my sister and her girlfriend at their house. When we did what we had to do and went back on the highway there were a lot of reckless drivers. Some people go from lane to lane without using the lights that they're supposed to use. My father put the light to go on the other lane and this guy cut him off the road and almost crashed into our car. He was speeding and plus there was full of traffic. We didn't know if that was a guy or girl but we were nervous but glad that we were safe.

My parents are crazy and so is my sister and her girlfriend so they were looking for the guy so they can beat him up for that. We ended up seeing him until he went into another lane. I kind of thought chasing the guy down was a good idea but he wouldn't learn anything.
