Could you write down how you feel about the office and wanting to switch to the other one and show it to her? I think a lot of people (me included) would struggle to talk while they could hear other people just outside. It's hard enough to talk as it is! I hope you can let her know that you would like to switch to the other office - as long as she has times free to see you in at that office then I think the choice is really up to you. if ok
