The only reason I'd tell someone is because I've seen enough verbal signals from their facial expressions to know that they think I'm either a bit off, snobbish, or whatever. To me, it's like asking why I'd tell people I'm gay (since I am as well). I'd either tell because of guilt that I'm not giving enough trust to a close friend, to educate others, or to close any further questions about myself. It's not really a big deal for me unless people start making totally uneducated assumptions about who I am as a person because of the different things that make me unique. Basically, for me, telling something like that about yourself just means that I trust you and an opportunity to talk about the condition or my way of thinking in order debunk any assumptions about who I am as a person, it's not meant to be an attention starter, but it is meant to make people aware because if you're something, why not be proud of who you are? It's only right to accept yourself and be comfortable with it, the fact that many people don't realize this is, to me, what brings shame to people with these conditions and have to suffer in silence just because they believe that society won't be accepting of them.
