Bonenkai

Today university staffs and teachers gathered and a big year-end party called "bonenkai" was held.

I eat delicious meats, sushi, fruits, and drank alcohol a lot.

Songs and showy dance by Brazilians were presented as a sideshow act.

After that, a lottery event that contains gorgeous prizes was performed.

I couldn't get anything, but they were really fun.

The literal meaning of "bonenkai" is "a party to forget the year", and it is often held in Japan to forget the hardship of the year.

However, since I still have a lot of work remain, I cannot forget this year yet.

忘年会

今日は大学の職員や教員が集まり、盛大な忘年会が行われました。

美味しいお酒にお肉、お寿司にデザートをたらふく食べました。

余興としては、ブラジルの方々による歌と派手なダンスが披露されました。

その後は豪華賞品が当たる抽選会が行われました。

私は何ももらえませんでしたが、とても楽しかったです。

「忘年会」は、年末にその年の苦労を忘れるために行われる行事です。

しかし、私はまだまだ仕事が残っているため、「忘年」することはできません。
