They joined what they joined. They lent their support and their moral approval. And, in so doing, they bound themselves to everything that came after. Who cares any more what particular knot they used in the binding?'

Thanks - both very helpful comments!

How do you edit your own work? Do you even like editing your own work? (If not, how do you motivate yourself to edit your own work?) What do you like about having an editor review your work? (Do you find it difficult or comfortable to receive feedback?) All advice and thoughts welcome!

My context is commercial children's middle-grade fiction. I wouldn't mind if they are being used with consideration, but I don't think a text needs to have comma splices on every other page, throughout a 240-page book, for example.

I take your point, but the avoidance of comma splices is mentioned in practically all grammar guides, both UK and US. (UK copy-editors, by and large, follow New Hart's Rules for guidance.)

(This is what kids are being taught in the UK.)

I'm afraid so, but all authors use them! You go ahead and write! It's the copy-editor's job to catch the comma splices :-)

Ooh, this sounds exciting! It was great to see you tonight! x
