We all could take some lessons from Cats.. If they don't want to see you, they will not see you. They'll roll their heads, look in your direction, and look right through you, but never will they see you even by mistake; if they won't want to..
Never will they put on a show like, 'Ah!! How did I miss you standing there!?' That's for us humans..
A cat will proudly sit right in front of you, proclaim in his majestic silence that you are trespassing his territory and that it will never be the other way round..
He'll make you wish that you'd better vanish somehow than be humiliated this way!
And the puny domestic cat is not even the King - that's for a bigger cat - But he'll hold the airs of one!
Now, that's the kind of a fierce feline egotism (read self esteem) that we sometimes need for ourselves..
