The Ghost in Trap 5

In the ladies toilet at work you can hear a strange noice coming from trap 5. There is a white box that you are supposed to put your used 'ladies stuff' in and it has a lid that opens automatically if you wave your hand over it. But that lid is now opening and closing without anyone being in the trap. Must be a ghost.

In our loft a man from the council has put mice poison down as we have been house sharing with the little blighters for a few months. BUT this morning JD tells me that out of the 6 portions 1 has moved about 2 meters and 1 is gone. So maybe we dont have mice but a ghost! Or a Japanese lady who is living there without us knowing....
