The context of the following conversation is Alex has autism and has always found that they are very particular about specific details therefore they are always very careful.:
Alex says I tend to notice really small details about things when I do anything compared to most people..
The friend responds Is that because of your autism?.
Alex responds I guess, but I am such a high functioning person with autism that sometimes people don't even notice anything is different about me..
The friend responds If no one told me you had autism I would not know..
Alex responds I guess that is good because sometimes I feel like people will judge me because of it..
The friend responds They shouldn't do that because you are a very bright and intelligent person..
