Ayako went to Sapporo to do something for Shimizu.

  In the morning, I stood at the crossing for the first time in this new academic year. It was not so cold, and the school kids looked happy and merry.
  Ayako left home for Sapporo as I was standing at the crossing. She was going to see our oldest daughter Haruna, and go to see Shimizu, our brother-in-law. She was asked to do something concerning his bank account.
  In the afternoon, I walked toward the Tomakomai river, and on the way back, I bought bread for breakfast.
  Ayako returned home around 4:00.
