Many weeks ago When I lay down on the bed I wanted to go to the toilet but I can’t open the door so I was thinking my mate was using it. therefore , I was walking to a friend’s room but I was seeing my mate it been talking with my friends. I feel very wonder so I told to my mate. After that we are been going to my room and open the door but the door is open as usual. Now we are was wondering why The door won't open or that the who was using it!.
