It's'not the first time I get that: "Show, don't tell". I didn't always understand it until it was pointed to me today. I use past continuous quite often. So the answer is simple: use preterit instead. But I don't much like that idea. After all both tenses have their usage and using preterit for an on-going action sounds plain wrong to me.
Why is past continuous even considered as telling rather than showing?
