There is a gift in simply being present with someone, even if the encounter lasts only 30 seconds. When I make eye contact with the supermarket clerk or my table waiter, my eyes say "I see you. You are not a thing to me. Or merely an appendage to the cash register. You are a person."
As we rush through our days, let us stay conscious of each interaction. Remember that everyone we meet is a God-holder. Honor each person with eye contact and a smile. It doesn't matter if the person smiles back. We're offering a gift, not a trade.
