Welcome back from your Obon holiday. We hope you had a nice time whatever you did.
It has been warm in Tokyo, but now we are in the mid-summer weather.
We have a new phrase for you today, duty calls.
This means you have to get back to work or do a specific task.
Example 1
It was great seeing you again, but duty calls. I have to get back to my office before my boss wonders where I am. Call me sometime.
Example 2
I really don't want to go back to work, but duty calls. We'll see you again next week.
