A bit of a convoluted narrative greatideas; and, I have to say, I made an audible sound when Chris was run over, in a very matter of fact sentence. The money rolling in was a clever use of the prompt.

And, to offer a bit of writing support, when you include direct speech into your piece - you're putting in someone's sentence - and that sentence starts with a capital letter. It might seem wrong, putting a capital in the middle of a sentence, but it needs to be there. You've done this 4 times, and only once did you capitalise. The other thing to be mindful of, from a grammatical place, is that before direct speech, you will need punctuation. Usually this will be a comma, and again, in your four examples, you would need a comma in each case.

Of course, it's easier where a sentence starts with direct speech. The fullstop from the previous sentence is your punctuation, and it makes sense then to start with a capital letter.
