When the supermarket clerk tallied up my groceries, I was $12 over what I had on me. I began to remove items from the bags, when another shopper handed me a $20 bill. "Please don't put yourself out," I told him.

"Let me tell you a story," he said. "My mother is in the hospital with cancer. I visit her every day and bring her flowers. I went this morning, and she got mad at me for spending my money on more flowers. She demanded that I do something else with that money. So, here, please accept this. It is my mother's flowers."

My neighbor, Jim, had trouble deciding if he wanted to retire from the construction field, until he ran into a younger man he'd worked with previously. The young man had a wife and three children and was finding it difficult to make ends meet, since he hadn't worked in some time. The next morning, Jim went to the union office and submitted his retirement paperwork. As for his replacement, he gave them the name of the young man. That was six years ago, and that young husband and father has been employed ever since.

While going through a divorce, my mother fretted over her new worries: no income, the same bills, and no way to afford groceries. It was around this time that she started finding boxes of food outside our door every morning. This went on for months, until she was able to land a job. We never did find out who it was who left the groceries for us, but they truly saved our lives.

I forgot about the rules on liquids in carry-on luggage, so when I hit security at the airport, I had to give up all my painting supplies. When I returned a week later, an attendant was at the baggage area with my paints. Not only had he kept them for me, but he'd looked up my return date and time in order to meet me.

Leaving a store, I returned to my car only to find that I'd locked my keys and cell phone inside. A teenager riding his bike saw me kick a tire and say a few choice words. "What's wrong?" he asked.

I explained my situation. "But even if I could call my wife," I said, "she can't bring me her car key, since this is our only car." He handed me his cell phone. "Call your wife and tell her I'm coming to get her key."

"That's seven miles round trip."

"Don't worry about it."

An hour later, he returned with the key. I offered him some money, but he refused. "Let's just say I needed the exercise," he said. Then, like a cowboy in the movies, he rode off into the sunset.

One evening, I left a restaurant just ahead of a woman assisting her elderly mom. I approached the curb and paused to see if my arthritic knees could climb it. To my right appeared an arm to assist. It was that of the elderly mom. My heart was so touched.

I was balancing caring for a toddler and working a full-time job, all while my Navy husband was on extended duty overseas. One evening, the doorbell rang. It was my neighbor, a retired chief petty officer, holding a breadboard loaded with a freshly cooked chicken and vegetable stew. "I've noticed you're getting a little skinny," he said. It was the best meal I'd had in months.

I saw a dress in a consignment shop that I knew my granddaughter would love. But money was tight, so I asked the store owner if she could hold it for me. 

"May I buy the dress for you?" asked another customer.

"Thank you, but I can't accept such a gracious gift," I said. Then she told me why it was so important for her to help me. She'd been homeless for three years, she said, and had it not been for the kindness of strangers, she would not have been able to survive.

"I'm no longer homeless, and my situation has improved," she said. "I promised myself that I would repay the kindness so many had shown me." She paid for the dress, and the only payment she would accept in return was a heartfelt hug.
