A couple years back, as i am travelling on a major highway, i noticed that i am following a semi. We are crossing lanes etc, and he is being a very good driver.
I noticed the "Hows my driving" sign on his rig. I called the number.
1st spoken words on the other line was, in a grizzly voice, " Whats he done this time".
His tone of voice changed instantly when he found out the reason for my call. Said he doesn't get many positive calls. I am sure he enjoyed his job just a little bit more, at least for a few moments.
I agree, we are always quick to criticize but should strive to compliment, when deserving.
