Wait. You can SEE what people expect?
Wow! What does it look like? What is the appearance of an expectation? Do they have colors? If not, how do you see them? Are you psychic?
You might on some occasions see me kneel in front of an icon of Dominic. I'd be interested to know what else you saw at that time. But I can tell you confidently that you would not see an expectation that I would receive treatment any more special that that which you receive from God. To God each one of us is "special."
I'm holding my icon of the Blessed Mother right now! Quick! What am I thinking?
