This one is probably for JMG and his entire audience, as it sounds kind of obscure to me: Does anyone know if there is some magical power to having a chestnut in front of the entrance to one's apartment door? My Filipino neighbours have had a chestnut on the floor in the recessed part of the floor in front of their hallway door for as long as I can remember, maybe months or years, and yet the building manager vacuums the hallway every week. So either somehow the manager is ignoring the chestnut, or if the manager is throwing it out, my neighbours are replacing it. They seem like nice people, the only thing remarkable that I know of about them is that the adult son is a very successful player type.
