At是一個點。假如你說某個人「at某個地方」，你一定找得到他。因為他就在那一點上。坐在桌子前，叫做sit at the table，和你約在某咖啡廳碰面，是meet you at the coffee shop。當然在某一個門牌號碼前面、看著某人，很自然地也都是用at。At是一個點。
On是一個面。我住在二樓，用I live on the second floor。在某條街上，想像，站在那裡，抬頭挺胸，是一種平面概念，用on the street。在火車，在捷運的車箱上，你不是擠在一個空間裡，可以伸直腰，站在平面上，這是on。那在飛機上呢？想想這個規則，on an airplane。On, 是一個面。
In是一個空間。空間可以大到是宇宙、山川、國家、城市，也可以小到一個車子、杯子、眼睛。所以是in the mountains, in the river, in Taiwan, in Taipei, in a car…。In是一個空間。
