I have a memory that I always keep in my mind safely. When I was in Japan I stayed in the third floor of a college dormitory. There was a vending machine at the first floor, right after the dormitory's entrance door, which sold canned drinks adjusted to the current season.
My favorite drink from the vending machine was Lipton Lemon Tea. In fall and winter the tea was served hot while in the spring and summer it was served cold.
I remember going out of the room in the middle of freezing night and walked downstairs to the vending machine just to get a hot Lipton Lemon Tea. It was my most favorite moment ever; sipping the warm lemon tea in the silence of the night.
