在雨夜写信给亡母的人想起了小时候和母亲放风筝时候的一件小事，他在重新的回忆中理解了这件小事的意义，当时幼小，只顾风筝，现在自己却不知不觉也陷入了与母亲相同的困局。和最亲密的人对话，永远是难题。

When writing a letter to his deceased mother on a rainy night, a man recalls something in childhood when he was playing a kite with mother. He understands something meaningful during the recalling. At that time, he was a little boy, now he unconsciously involves the same dilemma as his mother did. Talking to the most intimate person is always a problem.
