use of "since" in the past tense is correct or not?
Can we used "since" in the past perfect continuous tense, can't we? Or We used "from" in the place of "since" in the past continuous tense? For example: I had been reading a novel since 2008.(past perfect continuous tense). We write this sentence in past continuous tense form. I was reading a novel from 2008.(past continuous tense) Both the tenses are correct? And both the tenses represent same meaning?
