When mothers get together they talk about babies, fathers talk shop, pet-owners talk about their pets and girlfriends? They gossip and exchange notes... Oops! Scratch the last bit and let's talk about pets instead.
Did you know that some people keep fish to prevent their home from being burgled? In this part of the world where charms are still used to put home-residents into a tranced sleep, it is believed that if there is anything that is wide awake at all times, the charm will not work. So what animal does not sleep or does not appear to be sleeping? The fish, of course. That is why people keep an aquarium of fishes inside the home.
I have friends who have pet dogs are sometimes in a dilemma when they are planning a trip. They need to get someone to take care of their pets. Some would even send pets and pet beds along to their friends or relatives' home. So much for living a carefree life. To each his own, of course.
