Basically I mistook his beanie hat for a whiteboard cloth (we were sitting in algebra class together, and we were doing problems on dry erase whiteboards), and I tried to explain that I'm vision impaired so how could I know the difference without getting really close, but he just wasn't having it - he took it to mean I was insulting his fashion sense and wouldn't take any explanations. *sigh*
I mean, that was like 11th grade, so almost 20 years ago, but still!
