Why does the speaker say "wanted" with past tense?
Native speaker’s answer
Rebecca
The speaker here uses past tense because the thought he had, which is "give you a chance to think about your own style", is a thought he had in the past, and still had when he did this presentation (in the present). Therefore, "wanted" or "want" could be used here and be correct because "wanted" here refers to a thought, not an event that was clearly in either the past or present.
