Deaf and dumber

The cell phone is often confused with the contraption we used to make with tin cans and string. If you tied the string to the bottom of the cans, pulled it tight, and hollered loud enough, you could hear each other in the can.
It seems some people, especially those in crowed places, believe they need to holler loud into their cell phone like it was a tin can phone, so the other person can hear them. I ride the Long Island Rail Road to Manhattan and it is a guarantee someone will decide to have a phone conversation they desire to share with everyone on the train. The railroad makes announcements to please not use the cellphone to annoy others, but those who are annoying others are talking so loud they can’t hear the annoucement.
The best cell phone screamer happened yesterday when I was parking the car. This man was standing next to a building with a cellphone on his ear screaming “HELLO” over and over. I found a parking place, parked the car, got out, and walked toward my destination, all of which took about five minutes. As I approached the building, this man was still standing there shouting “HELLO” over and over and over. Seems to me he could figure out the person he was talking to wasn’t there anymore. Or maybe they were and they wanted to find out how long this lunitic would say “HELLO”. Just Say’n.
