...The need to have a space, both real and metaphorical to write....

From my point of view, it is very necessary to have a special space to write and clarify your ideas. But, I think that in order to have ideas is very necessary interact with others all the time.

Virginia Wolf shows this personal space to write with the idea of a room created only for her and her thoughts. In this way she express the need of being alone. For this reason, to contrast her feelings with the real world it was necessary to find a quiet place with little interaction with the outside. On the other hand, if you want to write about something you must interact with the real world. If you are a good observer and if you are interested on interact with people you will have more to write about because you will have more anecdotes.

To conclude, the writer need a space to write what is happening around, but this does't mean that you must be always alone.
