I don't find it any harder to use the shift key, or the buttons in the lower right corner of the keyboard where the period, comma, or question mark are located. It's just being polite. Writing a civil reply has nothing to do with it. It's more like trying to pound a little common sense into some ones head. I'm sorry you took it that way, but maybe if you ever have to write something on a job application you can think back to this thread and help yourself. Have a nice day.
