"can kindness change the world?" In my opinion it has multiple times. The whole world at once? No. It seems to be gradual. Could it now? I don't think so. Kindness is linked to selflessness and it feels like the world is a bit selfish.
@kyra-w I hope it doesn't happen again. I like your tenacity to try and make the best of a bad situation, or an annoyance at least. Glad someone as positive as yourself is around.
