Seven in the morning, water still glassy: the run is done, so it's a swim back — board under one arm, foil trailing behind. 🌊 Part of the deal.
Jam tujuh pagi, air masih rata kayak kaca: run-nya selesai, tinggal berenang pulang — papan di ketiak, foil ikut di belakang. 🌊 Ya begitulah.
เจ็ดโมงเช้า น้ำยังนิ่งเหมือนกระจก จบรอบแล้วก็ว่ายกลับ หนีบบอร์ดไว้ใต้แขน ไฮโดรฟอยล์ตามมาข้างหลัง 🌊 มันก็เป็นแบบนี้แหละ
