不论在生活中还是网络里，人人都会有朋友。如果没有朋友情，生活就不会有悦耳的和音，就如死水一滩；友情无处不在，它伴随你左右，萦绕在你身边，和你共渡一生。 友情，是雨季中的一把小伞，它撑起了一个晴朗的天空；友情，是风雪之夜的一杯淡茶，它能将寒意驱走，带来温暖；友情，是迷途中的一盏灯，它在你迷失时给你方向……人生漫漫，若能拥有一段地久天长的相知相伴的友情，生命亦无憾。 大千世界，红尘滚滚，一年又一年的风风雨雨，几许微笑，几丝忧伤，随着时间小河的流淌，许多人和事都付之东流去。但有一种人却随着时间的推移，你与ta的交往，如陈年酒香，沁人心肺。你与ta的友情是世上最珍贵的情感。这种友情是一种最纯洁、最高尚、最朴素、最平凡的感情。也是最浪漫、最动人、最坚实、最永恒的情感。 小时候，友情是简单的一个玩伴，是一份哭哭笑笑的天真无邪。儿时的友情是真切的我和你，可以肆无忌惮的吵架，互相赌气撅起的嘴，片刻之后又携手言欢。那时的友情是那一块小小的糖，甜甜的味道，永远留在了儿时的记忆里，无论何时回味起，都是美滋滋的。 长大后，友情是一樽透明的酒杯，举杯邀明月时，对影成三人。失败或落寞时的酒话连篇，ta不会觉得你烦。友情，是伤心不必躲在一个角落悄悄地哭泣，ta默默地陪你，告诉你在哪里跌倒的就在哪里爬起来。于是，成长里有我们友情地久天长的足迹。
