In the nature of things , the twins would be using the map outside class hours , at night , while sneaking around outside gryffindor tower 当然,双胞胎会在课外时间和晚上离开格兰芬多塔楼时使用地图。
They ' d be on the watch for anyone hanging around where they currently were and where they planned to go , not for anyone or anything safely tucked up in gryffindor tower for the night 他们会小心提防他们附近的人或者是他们目的地附近的人,但却不会注意到乖乖待在格兰芬多塔楼里的人或物。
