Ishikawa-san shows up in several of these. She was one of the first staff members that really talked to me when I moved here and didn't know any Japanese. She introduced herself as the "School Nurse", though I later found out she was the custodian. I'll never know whether that was a joke or a genuine mistake, but in any case she will always be Tuesday Nurse in my heart.
Unfortunately, she moved away during the staff switchover in May ;( That happens a lot out here.
