求翻译：今天在外读书的姐姐回家了，很久没有看到姐姐了，发现姐姐和以前长的不一样了，比以前更漂亮了。姐姐回家时给我们带回了很多东西，弟弟和妹妹都十分高兴，晚上又和姐姐在一起吃晚饭。是什么意思？

Reading today's sister went home, long time no see sister, sister and before long found to be not the same, more beautiful than before. Sister went home when we brought back a lot of things, brother and sister are very pleased, and sister together again in the evening for dinner.
