Where have all the flowers gone

After I'd eaten my weight in food at Curly's, I was heading back to subway with my doggy-bag. I muttered under my breath about not buying warm gloves. At -6 degrees, it definitely feels long overdue.

At the entrance of the yellow subway line, I saw a homeless man. He was wearing cloth wrapped around his feet (shoes), pens stuck into his ears (muffs) and was folding some extra clothes into a black trash bag (home), which already had in it a few empty plastic bottles and a bag of chips. That was it. All his belongings.

I looked at the brown bag in my hand, then at him. I said, "Excuse me, would you like to have this sandwich?". He flashed a toothless smile at me, and extended his hand. I handed the food to him and as I turned back, he pulled my arm. I can't tell for sure, but I think he was holding his arms open to hug me. He had dark grime under his fingernails. He probably sensed my hesitation; he withdrew his arms and said, "Thank you, thank you, thank you, thank you!" with the same toothless grin. I gave him a hurried smile and continued down the stairs. Once I was on the platform, I patted off the dust from his hands on my coat-sleeve.

Did I just do a good deed? I don't feel so good.
