Someone once said "Eyes are the windows into the soul". In Patrick's case, the curtains remain firmly closed.
In fact, if he just stands there, staring at you with his normal face, you'd never be able to tell quite what he's feeling. He could despise you for some unknown reason. He could be wondering how to get on your good side for his advantage. He could be totally apathetic towards you, seeing you as only another blob in a ...blob-ful life?
Hell, he could be thinking about what he had for breakfast. Who knows?
