So there is a statement that is often made about children with Down syndrome that is often corrected. That is "they are always so happy". And the retort is that they have a full range of emotions just like everybody else. And you know what? Both are true. It is true that we should not belittle the humaness of any person by saying they are always anything...especially something like happy that could be perceived as indicating that they aren't capable of any other emotion.
