@Tamasg Yeah true. I remember one time I was on the train, and a random sighted person said to me "Hey! There's another blind person just down the car! Don't you two know each other? Why aren't you sitting together? Here, I'll take you to him." I was like "No, I'm traveling alone. We're not together." Then the other blind person overheard the conversation, and it turned out we'd known each other for years. So we sat together and chatted for the rest of the train ride. I was so tempted to pretend I didn't know him at all, just so I didn't validate this random sighted person's stereotypes.
