nostalgia

what is nostalgia? is it the smell of my crayons hiding behind my sketchbooks, or the smell of food as I pass the old street vendors? you can say whatever you want. the missing of your home, the missing of your life. but you miss something, it doesn't feel clear, but what is it? I don't need a dictionary, I don't need someone to search it up, nor do I need some robot to correct me. you feel something, but nothing is happening, so what is nostalgia? the opinions of nostalgia are quite different. the missing of something, the peace you left behind, an unpleasant memory you remember. God they're all so different, for me? it's just... "something" you can say nostalgia is the rain outside your window every afternoon, you can say nostalgia is the bicycle that no longer works to go to far distances, you can say nostalgia is the puzzle piece you found under your bed. you name it. you feel it. so tell me, whats nostalgia to you?
