<p>I think it is one of those things that you don’t need to tell the world, but in a close relationship, it could get awkward to hide- if it is noticeable. I think the difficulty is that the term “CP” is very broad. Your situation is very mild, but your room mate could think it is more serious. Meet your room mate first, but then you could say something like you posted " I was born with a mild motor difficulty in my legs, and I walk pigeon-toed, but it has not effected me otherwise and I am fine. It was called “mild CP” and I’m used to it. It has not stopped me from doing what I want to do". This way she understands that you are not doing this on purpose, and that you don’t want to be treated differently.</p>
<p>I think by defining it, you don’t leave people to their own imaginations. It’s possible that your roommate may think “CP” means something else if they are not informed about it.</p>
<p>Likewise with something like Aspergers- which can affect relationships. Define it like "sometimes I seem distracted, or don’t get what you are saying to me, or I say something that you might find odd- but please say something if it bothers you. That way, a roommate won’t think you are acting some way deliberately and you can maintain the relationship. </p>
<p>Your roommates may have situations of their own, and much of it is working things out and being considerate.</p>
