"Beauty is in the eyes of the beholder." This has always stuck with me because it made me realise every single person thinks and sees the world differently. When you combine that with how I am autistic, this explained a lot, and caused me quite a bit of both relief and terror. Relief in the way that I know everyone is different to everyone, not just me. And terror in the way that I can't know if I have ever been the same as another person or even similar.
