#法国[超话]# 课间的时候，我拿着一杯咖啡进教室，一个女生看到，然后拿了一个蛋糕过来塞给我：“老师，送您一块蛋糕配咖啡！” 瞬间感觉好暖！这个蛋糕叫玛德琳娜(Madelaine)。我突然想起了普鲁斯特《追忆似水年华》里那段： « Et tout d’u coup le souvenir m’est apparu. Ce goût était celui du petit morceau de la madeleine que le dimanche matin, à Combrey, quand j’allais lui dire bonjour dans sa chambre, ma tante Léonie m’offrait après l’avoir trempé dans son infusion de thé ou de tilleul. »

（然而，回忆却出现了，那点心的味道，就是我在贡布雷的的某个星期天早上吃的小玛德琳娜蛋糕的味道，我去莱奥尼姑妈的房间和她说早安，她把玛德琳娜蛋糕泡在她的花茶里给我吃。）

我想假如我有一天离开洛林的时候，如果再吃到玛德琳娜蛋糕配咖啡，也会想起今天这个小女生，想起她今天给我温暖的小确幸。我真的，好爱我的学生们❤️#追忆似水年华##法国##法国文学# https://t.cn/RI4HYd4
