Please could you have a look at this little text:
I had preordered these books for a long time in a library, as they did not arrive I choose to find them by my self and finally found them. I had decided to do that because I had been tired of waiting.
Here is my question: do I need past perfect "had been tired" or would past simple "was tired" be better?
I think past perfect is better because both actions "deciding and being tired of waiting" happened before I found these books.
