I've noticed that and never thought anything of it ... until you mentioned it.
HERE - for those that don't know) This cannot be done left handed, because:
- You have to 'drag' a Fountain/Dip pen. Pushing it won't work.
- You drag the side of your hand trough the wet ink.
The advent of ball point pens put a stop to that - 'No. 1' anyway. So ... I had a lot of 'old school teachers' that just didn't get it. I can use a fountain pen ... just position the paper differently. My writing right hand is worse than my left hand .. they're bot legible though. Don't matter with Morse code ... I don't text.
