Hello, I am translating Survival Strategies for People on the Autism Spectrum, by Marc Fleisher and I find the sentence confusing: Picture a daywhen my last lecture finished on time, at 4.55 p.m. I would race out of the lecture room and across the university, past the maths building, then the sports and arts centre and up to the main road and bus stop. It is hard to believe anyone could run so fast. My whole body ached, I was so exhausted I often felt like choking. My doubt is that I am not sure if Could is referring to the past o to the future? Thank you.
