While I read an article, I came across the following expression that I can't still understand.
"If the wind picked up real bad to go in the bathroom and close the door, I had been so out of touch with the world around me that I hadn't seen any TV or read any newspapers."
If you go over above sentence, you can find that the past tense is used in If-clause and the past perfect tense is used in the main clause. Is there anyone who explains why the tense is different in both clauses in detail. Due to a different tense, I can't make a sense completely the sentence.
