the battle continues

Cartman used to have the privilege to sleep in my bed, recently he was rid off this privilege and had to sleep downstairs by himself. Of course he has been whining about this consistently. He keeps knocking at the door to upstairs at 6:45am every morning, fifteen minutes later, I will have to come down to walk him. Every morning, on  time, each time. A few weeks back, came the regular morning call, then somehow he went quiet. Then there was a white paw pushed the bedroom door open, a white shadow jumped right into my bed. Ah~~ Somehow he figured out to open the door, again! We used one of his old collars to lock the door again, well, sometime he can still manage to open it. Nan had to tie the collar really small and tight. Then, one day I found I cannot open the collar myself! It seemed the latch was halfly broken which resulting in the collar was stuck. Now, I had to do "hurdle" (in slow motion of course) when go downstairs and upstairs. The good thing is now since I cannot open it, Cartman cannot either. He resumed back to his knocking the door routine.
