TOD: Ach!
I'm gonna say the biggest pet peeves are cell phones -- in the hands of drivers who totally cannot remember why they are behind the wheels of their cars; in the hands of shoppers who suddenly stop dead in the middle of a store aisle with no regard for other shoppers; in the hands of anyone in an elevator who believes everyone is supposed to "shush" just because of the cell phone conversation; etc., etc., etc.
I believe the federal government should pass laws requiring people desiring to stand up, walk and be in public while using a cell phone to attain a license proving they can walk and chew gum at the same time.
Another pet peeve involving telephones: People who can carry on a face-to-face conversation in a normal tone of voice, but when on the phone speak as though making sure everyone within a 500-yard radius can hear him or her.
