I don't find open spaces noisier than cubicles but I am able to easily block out distracting sounds.

I am interrupted, and when I am is generally somebody giving me a useful quick update or an informal greeting from an office buddy when they notice I make welcoming eye contact.

I don't think I ever felt a lack of privacy in the office or expected it in any way? I wonder what kind of privacy I would need that the restroom doesn't cover, I'm sure there are some instances since it's been called out.
