Retired English Teacher
I think if the same thing is found in parts of Europe, Asia, and the Americas, there are more than a few robins. While this bias is no longer displayed, it wasn't that long ago that it was still prevalent. I have friends only a few years older than I am who went to Catholic school and were forced to write with their right hand. Nowadays, people who are left-handed are often seen as more creative, thanks to what we've learned about right-brain and left-brain tendencies.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
