In her 60s, Sonia eventually retired (after 40+ years of working for the Red Cross, helping separated families, but also various refugees... so you know, no big deal).
She moved out of Metz for the first time since the end of WW2, to live closer to her damn daughter, and to help her raise us.
She lived in front of the kindergarten my little sister attended, and close to my school. So after school, we'd go straight to her place for a couple of hours every day.
