Help me to check the reasoning and tell if I'm right
For I, in a hypothetical situation, we use 'were'
If I were there, he wouldn't act so snobbish.
I wouldn't go there if I were her.
and 'was' is used in past tense.
I was walking along the drag and heard someone called up my name.
I was about to give you a ring when I saw the advertisement.
However, I'm uncertain which to use when it comes with the word 'wish'
I wish I was there or I wish I were there?
How I wish I wasn't going to his house or how I wish I weren't going to his house?
