Yes, it does rather doesn’t it. I always saw it as strict but fair and still do to this day. Never was there any physical punishent either, it was always without that but still very effective. Often the comment from my mother would be “just you wait until your father gets home”. That always worked very well too!
Same here, Baz, was LH until I went to Grammar School at 10yrs old. There the nuns insisted everyone had to be RH. Now I am ambidextrous - which is very useful.
Being ambidextrous has advantages though, as you comment. It really is a strange one though isn’t it, there seems to be a lot of this that’s down to religion, left-handed people do seem to attract a lot of negativity when it concerns religion, there’s lots of information online if you do a search.
I also wonder if it’s something to do with the fact our minds work in ways that are related to our ‘handedness’ which brings another mystery – why do our minds work the opposite way to our 'handedness? Tasks and skills done with our right hands are controlled by the left-hand side of our minds. It’s also reckoned that, for instance, left-handed people tend to be more towards the ‘arty’ subjects, this comes from the right side of the mind which is supposed to be the ‘creative’ side.
With this kind of mystery it really isn’t at all surprising that humans are so very complicated!
The Nuns seemed to equate being LH to being in league with the devil. Strangely enough they never bothered about the fact that I was (and still am) also left footed!
Perhaps they never got round to that one? There is masses of conjecture to be found about this subject, below is a link showing some of the fears about left-handedness:
