This won't be seen, but when I was 17 or 18 I met a tall, Eastern European man on crutches who asked me to help him bring a couple of bags to the bus. They were very light and it was only a short distance, but he was incredibly grateful for my help. I remember he told me part of his story, he was undergoing or had undergone chemo. He was probably only in his early twenties. I will never forget him as despite his troubles, he emanated joy and positivity more than anyone I've met. He thanked me by giving me some pastries. A strange encounter but one I won't forget. I am naturally a pretty melancholic person, I wish I could be a quarter as positive as he was.
