On my way home from work tonight, a little girl stopped me in the neighborhood. She was holding a bag of lollipops and smiling as she asked, 'Brother, would you like to buy a lollipop? They're one yuan each.' What a brave little girl. Luckily, I had some change, so I bought one. The wrapper of the lollipop was a bit wrinkled, and I guessed she'd probably been trying to sell them for a while before she managed to sell one. After I gave her the money, she happily ran off to find her mom. It hit me that even these tiny ‘transactions’ can bring a little sweetness to a tired soul after a long day.
