This may be obvious but one of the reasons I write this blog, and write emails, and write Facebook and Instagram messages, is that it's difficult to express myself verbally. When speaking I try to be as concise as possible. I filter out the majority of the thoughts in my head. In groups, I end up sitting silent for long periods. It's very frustrating to tell a story when you have to stop and repeat every fourth word. It's much easier this way.
