I didn't play any sports, but my friends and I went to sing karaoke together! Do you like to sing? Karaoke was invented in Japan, and comes from the words "kara" (meaning "empty") and "oke" (short for "orchestra").
Many people are ordering Christmas cakes this week in preparation for the holiday. It's a tradition in Japan to eat Christmas cake on Christmas, after a meal of fried chicken (because turkey is very hard to find here).
