Cor, I really need to learn how to type/spell....
GJ, I think most people feel like they become public property when pregnant, and I think it depends on what sort of person you are as to how you feel about that.
I find it annoyed me a bit if I was in a rush, and I have some old biddy chewing my ear off, but most of the time I think, people are just like that, there is nothing I can do to stop it with out being very rude, so it is something you just have to live with. I don't see the point in getting worked up into a state about it.
And sometimes, depending on who is doing the ear chewing and what you are in the middle of trying to get done, it is quite nice to have someone interested enough to ask. It beats the blank depressing faces that never look you in the eye at all others time.
