I like your idea! I already believe most of the people around me are crazy, based on their actions. Like you said, if I let that invalidate what they say from them on, I'll cause myself much less stress. You can't expect a crazy person to act in a logical fashion!
BTW, my friend doesn't like cats so of course she would take what the bus driver says as gospel truth.
I did look up what the bus driver was talking about and it was some experiment done in Tokyo, published in December of last year. The researchers recorded the cat owners' voices and then played them for the cat to see what response they got. The cats lifted their heads, which they took to indicate the cats recognized the voice but didn't get up to look for the voice, which they took to indicate the cats didn't love their owners. Hardly scientific stuff. All that proves to me is you can't fool cats. You can pretend to throw a ball and a dog will chase after it but a cat won't. In this case, you can play the owners voice but the cat knows it's not really them because they don't see them near the source of the voice.
I bet dogs funded this experiment to give cats a bad name!!
