This afternoon I got a call from Brother. He wanted to talk about Mother, but he didn't know where to start. So he just started.
Sunday he and SIL had gone out to see her impromptu. When they got there (midday) she was still in bed, more or less unconscious. She had been sick, vomited in the bed, and then fell back asleep in it. They pulled her out of bed, washed her, washed the bedding, and tried to talk to her. But she was pretty unresponsive, and had no interest in eating or drinking anything. They had a lot of trouble just getting her to eat some toast and drink some fruit juice. They stayed over Monday as well. (Brother had to take a day off work.) She wasn't much better, but at least a little. Today they left. But they are—understandably—really worried about her.
No shit. With a story like that, of course they are. So am I, now that they told me.
