In our office we have the flextime system which means if I work overtime then I can shorten working hours in the same month. This month I've done many overtime work and have plenty of flexible time so I decided to go to office later than usual and go to see the eye doctor.
It's rather a popular clinic so I was afraid that I would need to wait long but fortunately I could have the checkup and talk to the doctor soon, and the result was good.
When I left the clinic I found I had 30 minutes free time before going to the office so I went to a small cafe near the train station, did nothing, just enjoyed a cup of caffe mocha.
Sometimes it's good to have this kind of idle time in our busy daily life, this 30 minutes was a precious relaxing time for me.
