陌生的红苹果

       一个微寒的夜晚，我搭上了从广州开往长沙的第58次列车。

       我躺在铺位看杂志，听到一声温柔的（a）：“小姑娘！”侧过脸，对面铺位上那位陌生妇女扬着手里的一只红苹果，对我说：“喜欢吃这个吗？”我笑笑，摇摇头。那妇女硬是把苹果塞到我枕边，我只好有礼貌地（b）。

       第二天一醒，发觉对面的铺位已经空了，苹果仍在我枕边，下面还压着一张纸条：

“小姑娘，早上好！我知道你怀疑我的好意，不敢吃。女孩子出门在外多加一个心眼是好的，不怪你。苹果是我到广州开会时一位朋友送给我女儿的，可我女儿正在北京读大学。昨天一见你，便觉得你很像我女儿，一样留着长头发，一样长着大眼睛，一样穿着牛仔裤，一样喜欢躺着看书，于是我猜你也和我女儿一样，喜欢吃苹果……”

       我很内疚，她能把我想像得同女儿一样可爱，而我却没有把她想像得像母亲一样可信。

       苹果送到唇边时，我感到自己得到的不仅仅是一个苹果……
