I'm wondering if this friend didn't want to go to NG's house themselves because they didn't want to offend NG. You know, since she's elderly, it would definitely be concerning if NG broke routine. But a lot of times the elderly don't appreciate being "checked on" when breaking routine when, say, if a person 20 years younger did a similar action it would not raise alarm bells. Does that make sense? Maybe that's why the friend chose to phone the daughter, instead. I've had my mom's friends call me for that same reason, out of concern, because they felt awkward talking directly to my mom. My mom is 77. Circumstances are a tad different because Mom has cognitive decline, but I think the premise is the same (not wanting to offend NG).
