“妈妈，看。小蝴蝶！”四岁的女儿手里捏着一只小蝴蝶蹦跳着向我跑来。“你看，多好看呀，是大哥哥给我抓的。”顺着女儿指的方向，我看见不远处有个男孩推着自行车向我走来。“老师，您也来公园玩啊？”他还没到我跟前就笑着和我打招呼，“是呀，放暑假了，我带女儿来玩玩。? “Mom, look at the little butterfly!” A four-year-old daughter bounced at me with a small butterfly in her hand. “Look, how beautiful, it’s from the big brother.” Along the direction of my daughter, I saw a boy not far away pushing me to the bike. “Teacher, did you play in the park?” He smiled and said hello to me before he came to me. “Yeah, summer vacation, and I bring my daughter to play.”
