Telephone call

Telephone call
This morning I went to the driving school.The cellphone rang when I'm in the bus.It's my mum,but I didn't get the phone.I called her immediately,but the answer machine said "Your called number is power off","It's strange" I thought.I called her again and again,but no one answer the phone.I thought,"Is there anything with my mum?"At that moment,the phone rang again,it's a strange number.I answer the phone,it's my mum.She said,"The telephone is power off.I'm calling you by the public phone." Then we talked each other.My mother always care of me,in her mind I'm still a kid even if I'm 31 years old.I love my mother.
In the past,I always spent many of time to work hard for get a good salary.But now I think I should spend more time with my family.
