The Annoying PPP

Xiaolu Guo discusses what it was like to move from China to England. It's a very interesting account, but the best part is when she talks about learning the language:

I particularly detested the past-perfect progressive tense, which I called the Annoying PPP: a continuous action completed at some point in the past. I felt giddy every time I heard the Annoying PPP; I just couldn’t understand how anyone was able to grasp something so complex. For example, my grammar book said: “Peter had been painting his house for weeks, but he finally gave up.” My immediate reaction, even before I got to the grammatical explanation, was: my God, how could someone paint his house for weeks and still give up? I just couldn’t see how time itself could regulate people’s actions as if they were little clocks! As for the grammar, the word order “had been” and the added flourishes like “ing” made my stomach churn. They were bizarre decorations that did nothing but obscure a simple, strong building. My instinct was to say something like: “Peter tries to paint his house, but sadness overwhelms him, causing him to lay down his brushes and give up his dream.”
