What is the difference between two sentences?
1.I did the work•(past indefinite)
2.I had done the work•(past perfect)
past indefinite when the action started in the past, finished in the past, and is not continuing now. ... The present perfect tells us that an action started in the past and it is still happening now, or it is something that happens regularly.
