Personal Space

Lately I have been thinking about "personal space". Humans seem to need it - for some reason they don't like it when you sit on top of them all the time or try to stick your nose up their nose or lick the inside of their ears. I really don't get it. What better way to show your love than to be right on top of your person?? Thank goodness, my best friend, Pixie, doesn't give a hoot about her "personal space".
