A grand piano??? (three question marks!) Do you play? I, sadly, have no musical instruments and no musical talent to speak of. I'd like a didgeridoo, though, just so I could have an excuse to say didgeridoo. As far as unusual things to have in your room go, I do have a knobkerrie (google that!) with a beautiful pattern woven in telephone wire around it.
I have read maybe 50 pages of Bleak House, which is one of the thicker ones.
