a)
- B: ... from the Internet, don’t you?
- A: ... do that a lot, don’t you?
- B: ... I shouldn’t really, should I?

c)
- Right, well, I think it would have to be copying work from the Internet, don’t you? → agreement
- I guess so. What about copying a CD from a friend? I do that a lot, don’t you? → question
- I don’t think the odd pen is a problem, is it? → agreement
- No, but you haven’t taken anything bigger, have you? → question
- That's a bit different, isn’t it? → agreement
- If I had, I wouldn’t tell you, would I? → agreement
- I think that’s pretty dishonest, actually, but people do it all the time, don’t they? → agreement
When we ask a question the intonation goes up, if we expect agreement then the intonation goes down.
