Discription of Events: Early Thursday morning as I was making a delivery for work, there usually aren’t many drivers out, I pulled behind this car and immediately noticed something was not right- there was a lot of movement going on not to mention I’m not sure why but the lady in the passenger seat flicked me off even though we were nowhere close (I didn’t know they even saw me). I’ve seen some reckless driving in my life, but never life this before. I’m not sure what made them act like fools trying to cause an accident especially while I’m in my work car just trying to work. I do believe I saw the driver hold up an item at one point that looked very similarities shaped to a gun. Be careful driving out in Norcross or anywhere.
