Having spent the whole day listening to the English lectures, focused on many interesting topics, I felt like I had (teacher: past continuous only - was having))the time of my life. I got totally swept up in them and wished there were more to come.
Here my teacher suggests that I use past continuous and says the past simple would be wrong. I agree that past continuous is a better choice here. But, as far as I know, I could use the past simple as well if I looked at the "situation" as a fact?
