But why is it significant to the elephant (or building)? OK, if the people in its stomach (room) gave it indigestion with their fighting then perhaps it might care (and respond by throwing them all out), but otherwise I see no reason why it would be interested. I don't care whether the bacteria in my gut believe in me or not, nor whether they ascribe their wars on each other to me or to ancestral hatreds ("Your mother was an E.Coli!" "Your mother had cilia!"), all I care is that if I get a stomach ache I'll pour some antibiotics down and get rid of them.
