Why is my son so shy? he is intelligent and a great writer but awkward at 17.

Introvert like me: Writers are often introverts. I was very shy as a child. Some kids grow out of shyness. If his shyness prevents him from enjoying life, you should seek the help of a professional psychologist. On the other hand, many children lose their shyness when they find a group to associate with that has their niche interest. Consider a writers group or a specific writers group such as fiction writers.
