Hi,
I was reading about the difference in meaning about the Past continuous and the past perfect continuous in order to be able to explain these sentences: "I had been walking through the park when it suddenly started to rain." and "I was walking through the park when it suddenly started to rain."
I found two possible differences and I'm not sure wich one is correct.
1.in the first sentence it started to rain after I walked and in the second sentence it started to rain while i was walking.
2.in the first sentence it started to rain long time after i started to walk and in the second it started to rain almost when I started to walk.
Thanks
