UPS review: driver

At exactly 6:30 PM Friday night on 31 Aug 18, I was backing into my driveway located at 232 Loudville Rd in Easthampton, Ma. My house happens to be on the crest of our street and since I have been living here have lost 3 animals on the street due to speeding and being on the crest. While backing in a UPS driver was speeding down the road, came upon me backing up and had to stop fast. He was so incensed that I was there backing, he gunned his engine to show his disapproval and anger. When he did that, I got upset and drove back out to when I caught up with him farther down the road tailgating another driver. I wanted to see if there were any numbers on the truck that I could call to lodge my complaint. There wasn't.
I have been a professional tractor trailer driver for most of my adult life.
I understood early on, that drivers HAD to be courteous despite others, had to be SAFE at all times despite what others are doing and had to be ready to make up for another motorists ignorance. And also be ready for any unexpected challenge down the road that may end up saving someone's life.
Through my years I worked in Boston and witnessed many inept actions where I had to be the one watching out and not hurt or worse kill someone who wasn't paying attention or doing something that put others lives at risk.
What this driver did tonight was uncalled for and immature.
I trust with GPS and manifests, you will be able to speak to this driver and let him know he needs to have an attitude adjustment.
It mat be Friday night, been a long day, dealt with many buttheads through the day and maybe his wife and him are having issues too...who knows?
But one thing is known, drivers that act in this drivers manner are ticking time bombs and as it always is, the innocent end up getting hurt!
Thank you for your time and consideration for my words tonight.
I have a five year old granddaughter who was in our yard playing at the time and that's really what prompted me to lodge this complaint. I wish the driver no ill will, but he needs to learn the importance of his job.
