I just back from outstation yesterday night and felt tired after took my dinner. Then I sleep early yesterday around 10pm. Suddenly my housemate call me around 12.30am morning to told me that somebody knock our main door and she ask me whether want to open the door or ignore it. Honestly, I sleep well at that time, I didn’t hear anything. Lastly, we really ignore of that person who knock our main door. This morning I just know that person is our another housemate which he lost his key yesterday. I don’t know why he not call our name while knock the door and he also can phone to us. This is not a first time.
