Let's suppose my friend missed a lecture by our professor Mr. Johnson today and he (my friend) wants to find out how it was.
- How was the lecture?
- Not much, Mr Johnson was telling jokes, so we learned nothing.
As far as I understand, Past Continuous ("was telling") is preferable here because it provides context or background info for main events ("we learned nothing).
Which would be more natural here: was telling jokes or told jokes? Or they are both equally natural in this context?
