Kindergarten class reunion = 800 yen ($8.00 €6.15)

My son attended his kindergarten class reunion held at the kindergarten today. Its participation fee was 800 yen ($8.00 €6.15). He left the kindergarten 6 years ago. After 6 years, half of kids got reunion. Kindergarten teachers also attended the reunion. They ate snacks, played games, enjoyed Bingo, talked each other, took members' photo. The kindergarten planed the reunion. I do not think the kids will plan their kindergarten reunion by themselves, so it may be the last time my son got his kindergarten reunion.
