Waves, unwavering waves... They come into existence out of nowhere and disappear equally suddenly. If you see, they are all so same but are actually different, some strong and some a bit weaker. But all of them equally determined to reach the shore, even at the cost of their own existence.
I still play this game of guessing the lifespan of each wave that I see, and even though it may be a few seconds, I still tell the wave, that you mattered, you made me smile.
