Yesterday I went to buy cigarettes, bought a pack of 20, gave the boss 50, and he gave me 40 in change. I pretended not to know, stuffed it in my pocket and walked away. Not far, the boss called out to me: "You didn't take your cigarettes!" I shed tears of gratitude, took out ten yuan and gave it to the boss: "You gave me ten yuan too much." The boss also shed tears of gratitude: "Young man, bring me the cigarettes, and I'll exchange it for another pack for you." Smoking the cigarettes that the boss exchanged for me, that pure flavor moved me again: "Boss, bring me that 50 from earlier, and I'll exchange it for a new one!" The boss, taking that 50, was also moved again: "Young man, give me the change I gave you earlier, and I’ll exchange it for you too." As I took the money the boss gave me back, I was moved again, took a mobile phone out of my pocket: "Boss, here’s your phone back." The boss's eyes were brimming with tears, trembling as he pulled out a wallet: "Young man, here’s your wallet back." At that moment, I couldn't hold back anymore, I knelt on the ground and hugged the boss's thigh, crying: "Brother, go to the hotel next door, room 304, and bring your daughter who is in elementary school back home!" The boss was surprised and sighed, turning back to the small shop and shouted: "Hongxing, don't hide, come out and go back with your husband!" I looked in surprise at the woman walking out of the shop, gently shook my head and said: "Brother, you can use that medicine." Taking the penicillin I handed over, the boss looked at the instructions and lowered his head in shame: "Forget it, I don't need this medicine, I'm an hv virus carrier, I'm sorry, young man!" My heart instantly turned cold, yet the boss's sincerity warmed it like never before. I said: "Brother, I almost did something I would regret for life! To be honest, that ointment is not penicillin, it’s dichlorvos!" The boss pondered for a moment, his tear stains still not dried, he closed his eyes and sighed towards the sky: "Young man, I actually have no illness at all, your honesty is truly touching, I really should die!" I was overjoyed, rubbing my sore nose, and said: "Boss, don’t say that, I’m the one who should die! Actually, your daughter is not next door, I was lying to you!" The boss waved his hand and said: "Young man, it’s okay, it’s okay, and look closely, this is not your wife at all, your wife is not even called Hongxing!" I suddenly realized, a warm current swirling in my heart: "Haha, brother, actually there’s nothing in my wallet, I just picked it up off the street." I took out the wallet and waved it in front of him, the boss said: "Young man, that phone is just a model, don’t believe me, look," he pulled out the phone, and the screen was just a piece of colored paper stuck on. We looked at each other, quietly sobbing, moved by each other. I said with a thick nasal tone: "Brother, actually that 50 I gave you earlier was also fake!" The boss shook his head slightly, a crystal droplet of tear falling to the ground: "Young man, giving you your change actually... sigh, bring it over, I’ll exchange it for you again." My tears burst like a dam, on the blurry retina he was slightly bent over, carefully rummaging through the cash box. I finally couldn’t hold back, saying: "Brother, actually I don’t smoke at all! I just came to spend the counterfeit money!" The brother patted me on the shoulder and whispered: "Young man, to be honest, this is not even my little shop. I’m just a lousy cryptocurrency trader, today I’m looking at trx."
