I don't get it.

I have never understood the movie 'Pretty Woman'. Why is she so offended by the Richard Gere character offering to put her up in a nice place with an allowance and all that? If she is a prostitute? Because her option is...?? Go back to the streets? They seemed amicable, why couldn't she just at least try it out? If she has intentions on tricking him into marrying her, it at least keeps him around. Right? I don't know. I've never really liked the movie. It was on today, so I watched parts of it. And I wondered what happened to Julia. She didn't even get old, really. She just looks strange now. Her nose is so much smaller and pointed than it was in this movie. In 'Ocean's 12' she looked a mess. In my humble opinion :)
