梨花(许地山)

她们还在园里玩,也不理会细雨丝丝穿入她们的罗衣。池边梨花颜色被洗得白净了,但朵朵都懒懒地垂着。

姐姐说:“你看,花儿都倦得要睡了!”

“待我来摇醒他们。”

姐姐不及发言,妹妹的手早巳抓住树枝摇了几下。花瓣和水珠纷纷地落下来,铺得银片满地,煞是好玩。

妹妹说:“好玩啊,花瓣一离开树枝,就活动起来了!”

“活动什么?你看,花儿的泪都滴在我身上哪。”姐姐说这话时,带着几分怒气,推了妹妹一下,她接看说:“我不和你玩了,你自己在这儿吧。”

妹妹见姐姐走了,直站在树下出神。停了半晌,老妈子走来,牵着她一面走着,说:“你看,你的衣服都湿透了;在阴雨天,每日要换几次衣服,教人到哪里找太阳给你晒去呢?”

落下来的花瓣,有些被她们的鞋印入泥中;有些粘在妹妹身上,被她带走;有些浮出池面,被鱼儿街入水里。那多情的燕子不歇地把鞋印上的残瓣和软泥一同衔在口中,到梁间去,构成他们的香巢。
