まとめ (Summary)

今日は昼からの観察でした。はじめての時間でどうなるか心配だったが短時間での動きがあり記録できてよかった。前回の反省も活かせた。予兆を大事にしていきたい。

• Today’s observation was conducted in the afternoon. I was unsure how it would proceed during this time of day, but i was able to record several behaviors within a short period, which was encouraging. I also made use of waht I learned from the previous observation. I want to continue trusting and refining my sense of anticipation.
