One lady comes home from work and no one is there to welcome her. No one except three domestic cats. Even then, it's hard to say if they are happy she is back or if they are tired of waiting for food.
Living with cats is no easy task; they make a mess while running around the house, beg to eat your dinner and sometimes even give you a mean glare for no apparent reason. Cats are unreasonable like that, but even so there is happiness to be found in their company.
