Come on Sarah or Come on, Sarah?

ryansamturner Which is correct?If I were saying:'Come on Sarah, you know that's not true'.Or'Come on, Sarah, you know that's not true'.I would say the first one, what do you think?

Come on, Sarah. You know that's not true. [ I think the situation calls for two sentences. ]

Thanks for the reply.
Can I throw another example at you. It's part of speech.

'She can't find anything.'
'Who can't?'
'The midwife, she said there's nothing there.'
Would you prefer to see that aa two sentences?
'The midwife. She said there's nothing there.'

Yes, but keep in mind that the first is not a complete sentence. This should be used only when "quoting" the people. The situation wouldn't otherwise come up in formal writing.

Also, following on from there.

The rest of the conversation goes as such.

'What do you mean? What can't she find?'
'A heartbeat, she can't find a heartbeat.' (Should that be 2 seperate sentences as well?)
'Sarah, listen to me, it'll be alright.' (Should that also be 2?).

Thanks
