@tekmansam Thanks a lot as always. I think #2 is gramatically correct but it's not commonly heard todays, right?

@NoobCube Thanks a lot for the feedback.
Let's say "if I were a bird, I could fly to you," does it sound weird? Or grammatically incorrect?

@NoobCube ありがとうございます。

@fingle thanks a lot for the help.

@Cathy_Z Thanks a lot as always. So according to your explanation, #2 sentence (Sometimes I wish I were a girl) should be correct and natural. But all the other commenters claim #1 is correct and natural. What could I think of this difference?🤷

@Cathy_Z Thanks a lot again for the links. All of them show the English rules saying you should use “If I were” when you use a subjunctive mood in a hypothetical situation. This applies to my understanding. So #2 (Sometimes I wish I were a girl) seems to be gramatically correct and completely natural to me, because being a girl is a hypothetical situation. Can you please be a bit more specific about the reason the other commenters insist on #1 ? Your thoughts?

Your Japanese is very good but I'm not sure about "だから難しいって言ったんです." What do you mean by that?

@Cathy_Z Thanks a lot again.
It’s good to hear how native speakers feel about this issue even though their feedback isn't always correct. I had a great lesson from you, thank you!
