Phone Call

Last night, when I fell asleep, I got a phone call. I did not answer it because I was sleeping. I saw the phone number, and I knew it was my home telephone number in China. Then I turned off my cell phone.
This morning, when I was on the way to school , I called back home. My mother said there was nothing important. Just she wanted to call my aunt but made a mistake to type my number.
Actually, I do not like people to call me at midnight, especilly when I was sleeping. If I remember to turn off cell phone, it would be ok. If not, I woke up then couldn't fell asleep again. You can imagine it. It would be terrible.
