When it comes to addressing a person with a disability, it is important to respect their individual preferences and autonomy. In this case, your friend has already stated that she doesn't have a preference, so it would be appropriate to continue addressing her by the name she has given you, which is Jane. Addressing someone with a disability is not much different than addressing anyone else. It is important to remember that having a disability does not change the fact that they are a person with individual preferences and feelings. However, it can be helpful to keep a few things in mind when addressing someone with an intellectual disability. First, it is important to communicate clearly and in a way that the person can understand. This may mean using simpler language or breaking information down into smaller parts. However, it is important not to talk down to the person or assume they are not capable of understanding complex concepts. Second, it is important to be patient and take the time to listen to the person. People with intellectual disabilities may communicate differently or take longer to process information, so it is important to give them the time and space they need to communicate effectively. Third, it is important to avoid making assumptions about what the person can or cannot do. People with intellectual disabilities have a wide range of abilities and interests, just like anyone else. It is important to treat them as the unique individuals they are and not make assumptions based on their disability. In summary, when it comes to addressing someone with an intellectual disability, it is important to respect their autonomy and individual preferences. In this case, since your friend has already stated that she doesn't have a preference, it is appropriate to continue addressing her by the name she has given you, which is Jane. Remember to communicate clearly, be patient, and avoid making assumptions based on her disability.
