Jean,
I e-mail my mom's RO periodically. He read the e-mail tonight and called right after to discuss it and speak with mom. I value the opportunity to be able to discuss questions that I am uncomfortable asking in front of mom/family. Sometimes my mom just wasn't ready to hear everything. Also, I agree with Bren about your brother needing time alone initially. My mom always came home exhausted and really needed to sleep/rest. I found that if someone aside from those living here was present she would try to stay awake and be the hostess. Rad really took a lot out of her.
I'm glad he has you to manage things....it's not easy at times.
