So, post-visit report:
My niece, Rikki, addressed her as “Auntie Susi!” the first night.
My sisters both like her; Rachel, the youngest, was the picture of hospitality, and kept trying to feed Susi, while Carol (the middle sister) talked and discussed with her in a welcoming manner, and also kept trying to feed her. Also, Carol’s kids, primarily Rikki, adored her. (And Rikki is an intensely smart little prodigy… a just-under-five-year-old who, for example, knows what a “triangular prism” is, how it is not a pyramid, and explained this to her aunt, at length)
My mother kept trying to be a caregiver, and of course, showering us with food (we have so much leftovers…), while my father talked with (at?) her at length, telling her stories, and, upon finding that my future mother-in-law collects coins and stamps, went through his personal coin and stamp collection for some things to send back to Germany.
Also, we visited the Cleveland Natural History Museum, where I volunteered as a teen and I gave her the tour that I once would have given when I was one of the astronomer’s assistants, and we also visited the Cleveland Art Museum and got to see their impressionists, and the Mugal art exhibit, and the Arms and Armor hall.
All in all, it was an awesome visit, and Susi now feels that she not only has me, but the rest of my immediate family to count as her own, and has deeper roots than she did last week–and we’re currently being very sappy.
