上一章下一章目录图片发自App从Zetor出来后,我很担心江蜜,但是她异常平静,只是兴奋不复从前。回程的飞机在飞行途中遇上罕见的暴风雪,重新迫降到赫尔辛基机场。当时已是开学前一天的傍晚,而风雪即使即刻停下,最早也只能做第二天的航班返回,学校的课也必定是赶不上了,索性不去想。坐在去往航空公司方面提供的酒店的机场大巴上,无论从哪个角度车窗哪个角度看到的都是相同的景象,大巴车仿佛一个隔离了时空的黑匣子,

上一章下一章目录Q图片发自App芬兰赫尔辛基的Zetor餐厅里,江蜜饶有兴致地给奶牛雕塑、红色的拖拉机、复活节彩蛋和不知名的草拍过照之后,一边抱怨餐厅为什么没有为传统美食“土豆烩”(小土豆,小肉丁和小香肠丁放在一起烤,配以甜菜块和酸黄瓜)准备勺子,一边和我探讨为什么复活节和复活节星期一餐厅营业时间都会有所变化。我忙着切两个巨大无比的鹿肉香肠,对于江蜜所谓的“探讨”,不过是有一搭没一搭地回应。她兴奋
