I ran back to Gunter and told him the bad news. He looked at me in disbelief, asking me what to do. Flashing him another apologetic smile, I begged him for a delayed payment. “If I miss this last bus to Prague, I’ll be late for the conference which is so important that I can’t afford to miss it!” I explained. “May I have your phone number? I will call you and return the money I owe you. I promise I will keep my word or you keep my watch!” I added, handing him my watch as well as my business card. Gunter accepted my business card but rejected my watch. He wrote down his phone number and gave it to me. “Just keep your promise, Sir.” A feeling of gratitude washed over me as I heard his words. Giving him a firm handshake, I jumped out of the car, made a mad run for the bus, and jumped onto it just before its departure.
Four days later, when I was back in Vienna, I called Gunter as promised. He picked me up at the bus station where he had dropped me off four days before. Beaming a warm smile at him, I gave him a big hug the moment I saw him. We chatted happily on the way to the airport. I told him that thanks to his generosity and timely help, everything had gone smoothly. When he stopped his taxi outside the airport, I paid him for the “double car ride”, back and forth from the airport to the bus station, together with a generous tip that he turned down. I also gave him an attractive souvenir I had bought at Prague, which he accepted with delight. We became good friends and kept in touch with each other regularly. I felt blessed to have such a warm-hearted friend like Gunter.

I ran back to Gunter and told him the bad news. Gunter’s face tightened with concern as he listened. “What are you going to do now?” he asked, his voice filled with genuine worry. “If I miss this last bus to Prague, I’ll be late for the conference. It’s really important!” I replied anxiously. I could see the understanding in his eyes. “Can I take your phone number and promise to pay you when I return in a few days?” I suggested, hoping he would trust me. Gunter didn’t hesitate for a moment. “Forget about the money for now,” he said kindly. “Just make sure you catch your bus.” He handed me his business card with a reassuring smile. A wave of relief washed over me as I thanked him profusely and sprinted back to the bus, barely making it before the doors closed.
Four days later, when I was back in Vienna, I called Gunter as promised. Gunter answered immediately, his voice warm and cheerful. We agreed to meet at the same bus station where he had first picked me up. As soon as I saw him, I greeted him with a broad smile and handed him an envelope containing the fare, along with a small souvenir from Prague. Gunter chuckled and said, “You didn’t have to do that, but I appreciate it.” He refused the extra money I offered, insisting, “The taxi fare is enough, my friend.” We shared a moment of laughter, and he suggested we grab a coffee the next time I was in Vienna. As we parted ways, I felt a deep sense of gratitude for his kindness and resolved to pay forward the trust and generosity he had shown me.
