Isn’t that what a beta’s supposed to do? Tell it as it is and find the stuff that’s wrong, whether or not it’s a pain in the ass? ;).
Honestly, like I say, I don’t mind hearing an ‘impromptu beta’. Seeing what someone else might think works can improve my own writing. CR and I have different styles, different ideas of what needs to be said and what doesn’t, how to do things, et cetera. Having someone else point out something that could be made better, to me, isn’t a bad thing and I have to say that I appreciate hearing a different take on what to do and how to do it. Every bit helps in the long run. Besides, while not a regular occurrence, I have caught myself (and apparently missed), finding sections I’ve edited/changed and forgot to delete. (I’m blaming that weird looking angel on my shoulder, I’m not sure why the horns are holding up the halo, but she always says not to ask, so...) Now that I’ve rambled on, though...
