An Elephant in the Room?

I love my flat in Edinburgh, but sometimes I really do wonder what the people upstairs get up to. Last year I was convinced I lived beneath a herd of elephants, and was hoping that my new flat would be somewhat quieter. But it was not to be. I don't know what they do, but it doesn't sound like it should be done at about midnight. My partner and I have come up with several possibilities. They either a) have a home gym (we've heard them on the rowing machine several times); b) have a home gym but have to move all the other furniture in the flat to be able to use it; c) have an obsession with rearranging their furniture late at night at least twice a week; d) are obsessive-compulsive feng shui practitioners; e) have a bed on casters (like we do); or f) have a pet elephant. I'm not sure how an elephant would cope with the spiral staircase in the building, so maybe that's not so likely! On the subject of elephants, if you're ever in Edinburgh I would highly recommend a visit to Elephants and Bagels, a relation of the more famous Elephant House (although you're more likely to be surrounded by students than tourists, HP fans and authors). Their warm bagels are just the job on a chilly Edinburgh day.
