New Year's Holiday

Today I spent slow-paced time with my family.

First I took a shower, had a breakfast, then played with my nephew and niece.

After that, I did my work of university until around evening, then my family went to a yakiniku shop (beef barbecue restaurant) to eat dinner with my brother's family.

I ate yakiniku after a long time, and it was delicious and satisfying.

Although it is almost night in Japan, I will go back to the area where I am working to avoid a major traffic jam.

I will be careful not to fall asleep and cause a traffic accident.
