I am travelling through Europe now. I saw many parting situations on a platform. I thought they spent the Christmas holiday in their home town. Someone gave a goodbye hug, some others blew a kiss through the train window. The one person who saw the other one take off sometimes runs with the train that had begun moving. BTW, I always remember the poem by Masuji Ibuse at a farewell situation. The original was a Chinese poem and he translated it into Japanese. I got a strong impression from a line of the poem. I introduce the line translated into English.
Life is only full of goodbyes.
