I wish I did...

Thank you for clarifying that, Davy.

Wish + would is used for complaints - I wish he´d stop that! ( but he´s unlikely to); I wish she would behave ( but as a rule, she won´t)

Wish+ simple past is used when one wants the present to be different.
I wish I were slimmer(but I´m fat); I wish you were here( but you´re not); I wish I didn´t have to work today but I DO!

Wish+ past perfect is used when you want the past to be different!
I wish I had studied harder for the test! ( but you didn´t, and you failed it!)

I hope this helps

I wish + past simple --- When you want to change an existing situation
eg I wish I was/were rich

I wish + would + infinitive --- 1. when you want someone to change a habit
eg I wish you would give up smoking

2. when you want to stop something that
is happening or not happening
eg I wish it would stop raining
I wish + past perfect ---- To regret something in the past



eg I wish I had worked harder before my exam
The important thing is to say " Is this a situation or something happening"
