Raindrop

I remember I wrote in my daily diary as an elementary schooler (maybe 2nd?) that the sound of raindrop, the bouncing sound onto ground, onto umbrella, was joyful and interesting Now? ... Whenever I recall that, I feel great sadness It also reminds me of what Schopenhauer wrote: When in my young days there was a ring at the door, I was pleased, for I thought, 'now it might come'; but in later years on the same occasion my feelings were rather akin to dread and I thought 'here it comes'.
