Here are some portions of an email my sister sent me:

[…] I was having a couple of sad days just grieving over Mom and what is happening in her head. She asked me if I wanted to come to her house Friday night for dinner. It broke my heart because she was sincere, and I would love to be able to go. And what you said about her reading you your card. Just feeling sad about it all.

Have you asked [name redacted] about the psychological test yet? I think we need to decide. Too much time passes in between conversations with Doctors and action. […] we need to talk more about decisions that may need to be made. Do you know if you are her power of attorney? That is another thing that we should get figured out for sure. Just because. […] Please talk to [name redacted] about the test. Or anyone you know who knows more about this stuff than me. […]
