I approached him very much like the nosy neighborhood curmudeon, I asked, sternly, "do you need something!?" "Not in a concerned tone, but rather in that tone that says, "get moving buddy, I own a house, I'm worried about my property values." I might as well have shrieked, "get off my lawn!
He asked for something to drink, I said, again curtly, "I don't have anything," and he shuffled, shoeless up the gradually steeped sidewalk towards downtown. My guilt got the better of me and I grabbed an old pair of shoes I never wear and a La Croix (I know what you're thinking) and I gave it to him. I was very pleased with myself, particularly because someone was driving by at that exact moment and got to witness my selfless charity.
After my awesome morning display of humanity, I leaned back in my chair, drank my coffee, but coudn't let go of a gnawing distaste for how I'd treated the man, how I really "treated" him. Even when I handed him those shoes, I did it with a preachy superiority. It's the only "gift" I've ever given that made me feel bad about giving it.
