Hmm…a previous plan…So, what you mean is that there’s ‘at least’ more than 1 plan? Or it’s just saying a plan made by someone before what actually happened?
I understand it this way:
What is happening now (wating, wishinng, etc.) is not what you expected / planned.
The past perfect is usually used for an action in the past that happened before another action in the past:
I had bought the tickets when Peter called me and said he wouldn’t go to the cinema.
What I don’t understand is why use the past perfect when the second action is not in the past but in the present (This IS not…)
Can I say ‘this is not what I planned’ and what is the difference between ‘this is not what I planned’ and ‘this is not what I had planned’?
