NY formulated the question :
Handedness is an interesting thing. I had lunch with a woman who ate
with her fork in her right hand and her knife in the left. I was
puzzled because I'd earlier seen her writing with her right hand. I
asked her and she looked bewildered: she was evidently so used to
eating with her fork in her right hand for any food that didn't
require a knife that she hadn't learned to eat with fork in left and
knife in right, and instinctively used her knife (on the rarer
occasions) in the opposite hand to the one she habitually used her
fork in.

Interesting, very!

I was born a sinister, forced at school to use my right hand to write
with by tying my left behind my back. At 71 it now feels very odd to try
to even try write with my left, but most other things I can happily do
with either hand. I am left permanently confused by left and right,
because I don't have a natural main hand. I have to think for a while
before laying out knives and forks at the table. I use most tools with
which ever hand suits the easiest access, or in repetitive jobs often
just change hands to rest one or the other. Picking up a handed item
like a circular saw, I would need to test it with both hands, to see
which hand worked best. I get confused when shaking hands with someone
as to which hand to offer and my hand writing has always been terrible.
I can though, beat most people with hunt and peck on the keyboard.

Our lad is left-handed. No stigma nowadays, of course, but it has taken
a long time to get him to stop getting ink all over his hand as it moves
across what he's just written :-)
