Haven't managed to damage objects with telekinesis.

Was trying to talk to Cecil while still running into the building. Grabbed and moved the chair instead. He fell over and died from the damage. Old people; what can you do? No sense of humour anymore.

The maid was upstairs, and the guards outside the door didn't twitch.

Once I stopped laughing I went back to my last save, so I don't know if there would have been hostility if I'd gone looking for it.
