Pros: one must subsequently think about what they want to say before it comes out of their mouth so they will have control over their worlds in a conversation. Other people in conversation will be clearer in their message so the recipient with this disorder will be able to understand them.
Cons: difficulty communicating on an intelligent level, distance from society and communication, being left behind in group conversation.
well the "as" makes it a simile. its an exaggeration method used to emphasise a certain feeling or action. in this case its used to emphasise a feeling of grief or sadness. Hope this helps!
