I spotted (发现;认出) him at the checkout counter, bagging at No.14. His arms shook violently as he placed a carton (纸板箱;纸盒) of eggs into a plastic bag. He wore a yellow plastic name tag on which he had written “Jerry” in kindergarten penmanship (书法). He looked middle-aged but his mental age must have been about 12.
Ever since I smiled at him the first time he bagged my groceries at my local supermarket, Jerry has followed me around like an adoring fan. His lack of boundaries makes me unfortable. I don’t know how to avoid being noticed by him. I don’t want to speak to the manager — my plaint could get him fired. So I start avoiding him.
There are other grocery stores, but I choose this one because it employs people with disabilities, from which my brothers have also suffered.
Last Wednesday after I finished choosing what I wanted, I turned around and drove my cart to Checkout No.3, hoping Jerry would not notice me and stay at No.14.
“Paper or plastic, ma’am?” Jerry’s soft voice surprised me from behind. “Paper, please.” I noticed that the checkout stand created plenty of space between Jerry and the clerk. In this situation, he knew where to stand. The clerk said to me: “＄27.30, please.” I handed my own cart, signed my receipt and stepped around the counter, where Jerry was holding my last packet of biscuits. He came towards me, stopping an inch from me. He was too close. I wanted to dash out of the store and leave behind the packet. Instead, I stood with my hand frozen on the cart. His eyes looked lonely — I knew they would follow me after I left the store. I wanted to apologize for my coldness. “I’m …I’m sorry.” A tiny voice inside me said. I tapped my head with my hand as if I had forgotten something. “Forgive me. I’m from New York City. I’m not used to people being so helpful.”
He laughed. I laughed. His eyes brightened. “It’s my job, ma’am. I like it.” he said. When he offered to push my cart, I didn’t care but nodded deeply.
