I worked for 14 hours today.
We have a lot of work,so I had to over time work.
I'm very tired.
By the way,cost of a call in bangalore is very low.
A minute cost of a call is about 2.5yen.
But price of mobile-phone is high.
It is about 45000yen.
Japan cost of a call include price of mobile-phone,
so Japan price of mobile-phone is lower than india it.
