It is said that the opposite of shame is pride or honor but most people -- and most countries -- have a lot more of the former than the latter.

Everyone knows that pets are part of the family but few want to admit spending $1,500 on Max's cruciate rupture or Jake's cataract surgery. Few also want to admit using a "poop patrol" service for their backyard or doggie day care. Nor does anyone want to admit the hygienic black hole known as sleeping with your pet, even though everyone does it.

The same man who has never wiped a counter in his own house will vacuum the seats, wash the floor mats, Windex the windows and refresh the air. And don't even think of leaving dirty fingerprints....
