Did not fix chapter 1, realised instead that I needed to take a bit from chapter 2 and a goodly chunk from chapter 3 and make an all new chapter between existing chapters 2 and 3 and have done so. Lo! it is Philosophical and Ranty and will I hope bring into somewhat clearer focus which bits of this character are meant to be likable and which not. (It's a real pain when you write a first-person narrator with certain character flaws who uses charm to get around some of them in some cases and she charms readers into thinking they're not meant to be flaws at all, or that you the author don't think they are flaws and are yourself somewhat less wonderful a person than is in fact the case.)
Also wrote a snippet of the beginning of the next chapter, which is now 6, because on rereading 5 someone had to realise that was suspiciously easy really straight the heck away. Running total just over 16kwords. Go me.
