Wishes (Insert puns and the end here)

Be warned, puns inbound! Bullets will be fired because this is the last part.

 

(Je)wishes!

In general

 

We use the past tenses to talk about wishes. 

More specifically, for the future:

• We use past tense modals would and could.

I wish I could get a better house.
I wish it would stop raining
  I wish my parents would let me stay out later.

For the present:

•  We use past tense.

I wish I lived in somewhere less populated.
I wish we were travelling first class.
Everyone wishes they had more free time.

For the past:

• We use the past perfect.

I wish I had worked harder when I was at school.
Mary wishes she had listened to what her mother told her.
I wish I hadn’t spent so much money last month.

An important detail that shouldn't be forgotten is that the form "If only" has the same uses and forms as the wish, it just emphasizes more on the fact that things wouldn't be the same if that "something" happened/existed/... 

With that being said, this is all I have to "teach" you (let's be honest, I just hope I taught you something useful since I'm really bad at explaining)

So...
