School starts in August next year? I thought it started in September.
I proposed that this is one good example of how grammar can confuse people because a preterite (started) is used to talk about the future.
She replied that it's an example of tense shift in indirect speech.
I didn't think so originally. But I can see how I thought x can be conceptualized as a reporting of one's own (inner) speech.
Does the utterance contain indirect speech? Yes, no, sometimes/maybe?
