My brother and I have pretty well mastered the art of getting what we want from the humans we adopted. They're pretty nice people, but they don't always understand us immediately. So, we have learned to sit patiently at the back door and look at them until they realize that we want to come in the house.
We have found that this approach works much better that making lots of noise and insisting that they let us inside. In fact, when we make too much noise, they generally ignore us. When we rush in without being invited, they chase us down and make us go out without so much as a nice rub between the ears.
We haven't quite figured out why they behave so strangely. We just know that they do. So, rather than try to change how they react to us, we just change our behaviors to get what we want.
We want to go inside for a few minutes to warm up and get our backs rubbed. When we're nicely and gently persistent, we almost always get what we want. They don't always act as fast as we want them to. Sometimes we have to wait a long time. Still, it almost always works.
Please don't tell them our tricks. If they knew that we were playing them, it might not work anymore. Shhhhh!
