16、下来之后，先是双手捧在面前仔细地看了看，然后又努起小嘴儿亲一亲，让张老乡看着眼眶直发热。他伸手拦住准备切西瓜洗水果的郭氏，说：“弟妹别忙，你听俺说话。这个女娃就是耿兰了？和她姐姐长得可真像哇！”“你见着她姐姐和哥哥们了？”“见着了，都见着了。这样吧，耿兄弟还惦念着他的老岳父和老岳母呢！要不咱们去老人家那里再细说？”“好好好，咱们去，咱们去。俺爹娘也老在念叨他们呢！”大家出来，郭氏锁了院门儿。耿兰拿着爹爹捎回来的书信，蹦蹦跳跳往姥娘家去了。郭氏回头对刘氏和裴氏说：“那俺们先去俺娘家啦！”妞儿也要跟着去，被刘氏拉住了，说：“俺们和你爹，你哥哥他们一会儿再去！”刘氏和裴氏站在路边高兴地挥手道别。刘氏
