I guess I understand the rules in subjunctive mood.
I am aware that this expression is giving some advice.
If I were you, I would....
I'd just like to get some double confirm about the usage.
I also learned an ELL post
The only context where were is appropriate after I is when the sentence is in the subjunctive mood
Some friend told me:
in American English, people use "I wish I was" to form a subjunctive mood sentence.
"I wish I was rich."
in British English, people use "I wish I were" to form a subjunctive mood sentence.
"I wish I were rich."
Is it that true?
The quoted text was from: https://en.wikipedia.org/wiki/Subjunctive_mood#English
Seems like they are placing it under "past subjunctive". Perhaps a linguist would correct the page. I would cross check the references for those sections first though.
