Inside of my  house recently became very cold becasuse of boiler was out of order.I and my friends didn't know boiler was not working when we slept. However, I was able to know that there was something wrong with boiler.I woke up in the midnight while  I was sleeping because i can't stand the cold. Moreover,my friends woke up in the midnight same as me. At that time, outside was warmer than inside of my house. I didn't want to go my home. therefore, our guardian decided to call boiler machanic as soon as possible.I really hope to sleep well at night.
