Do you still own the things you share?

I've finally got some people who don't live in this house reading my MS, and I have to say I'm a bit weirded out about it. When a new e-mail arrives from a beta-reader, I have this moment where I'm contemplating parts of my book and suddenly thinking, "Oh god, what will So-and-so think of this?!" Which is doubly weird, because I don't actually have any friends named So-and-so . . .

It's like, as much as I've been hoping this would be the work of mine that finally sees the light of day, on some level as I was writing and rewriting and revising, it actually didn't *occur* to me that other people would, you know, *read* this thing! This is my story--what are all these people doing reading it?!

It's also a vulnerable position, because I find myself fearing that people will think less of me if they read my writing and it sucks.

Oh well.

EDIT to turn one of these sentences into English and to complete my hastily-posted thought.
