There's a very friendly cat in the neighborhood where we live. We're not sure who she belongs to as she has no tags. In fact, we're not even sure if it's a he or a she. Since we've moved in we have found her waiting for us on the stairs, sleeping underneath our cars, hanging out with us in the garage, sneaking into the neighbor's house and under her bed, and taking over our deck chair. When we catch her on the porch she sometimes ignores us and sometimes, if she feels like it, lifts her head up at as, gives us a look as if to say, "Oh. It's only you." and then continues lounging.
Today I caught her on the deck and thought she just looked so happy.
