在外企上班的那段时间，朋友的生活特规律。 早上六点起床，被子是豆腐块儿，脏衣服入篓，书籍上架，鞋尖是一条线，随后就戴上耳机在公园跑几圈儿，回来洗个热水澡，换上正装，打早班卡，逢人便微笑打招呼，工作上进，生活愉悦，体重正常。 三年后，他觉得这样的生活太束缚了，厌倦了拥挤的早班地铁，讨厌了末班地铁回家，太刻意，失去了享受“自由”的乐趣，需要时间，需要呼吸。 辞去工作，就回家就考了公务员，日子真的就是朝九晚五那样，无拘无束，没有压力，没有变数，没有多舛。 他说，白天可以上班，晚上就可以经营自己的小书店，可以和读者讨价还价，谈王小波的小流氓，谈徐志摩的风流，...</p> <a target="_blank"

上周末我们几个朋友一起喝下午茶的时候，原本晴空万里的天突然阴沉下来，继而马上下起了大雨。刘姐突然一拍脑门说，糟了，我早上洗的衣服还晾在阳台上没收呢，窗户也开着的，衣服要被打湿了。我们宽慰她说，不怕，姐夫在家的吧，打个电话让他收一下就好啦。 刘姐抬起手机，戳开微信，边打字边说，没事，我给他发条微信，他会看到的。 刘姐的微信还没发出去，电话就先进来了。电话是姐夫打来的，姐夫告诉她，衣服他收起来了，然后问她人在哪儿，有没有被雨淋到，冷不冷，要不要他送件外套过来。 刘姐一连串地应声回答着，末了连说了好几次“不用不用，你不用过来，我不冷”，才总算打消了姐夫开车过来给她送外套的念头。 挂了电话...</p> <a target="_blank"
