Almost immediately, K bought F an airline ticket, and made reservations for some of the places she likes best in the western US. When F arrived they went shopping to get her sturdier clothes, and then it was off to Yosemite. They came back after a week and other friends threw a party for F, which I attended. She seemed fine to me, but K was hinting that it was like having a kid with you. Hard for me to visualize, as F is about my age.
After a trip to Sacramento to see F's relatives, she was sent by herself to a friend's out of the area with whom K had had a falling out (for many years they went to the village together).
The plan was for K to bring F out to Sedona, Phoenix and the Grand Canyon, but this morning I was surprised to receive email from K in LA that F had gotten so homesick, and had become such a burden that she flew home today, 12 days early. She said it was a relief, and is on her way to Phoenix later today.
