I was wondering if you could help me with some correct punctuation advice?
Have a look at this sentence;
"It isn't the car that's useless," whined Leo, "it's me!"
Is that the correct use of commas when I break off in the middle of a sentence? Also, should the 'i' in 'it's' be a capital if not, even if there should be a full stop after Leo?
I hope that makes sense, I've seen it done different ways and I'd like to get somewhere near the correct way!
Thanks in advance.
