Explanation:

This is one of the reasons why it is convenient to use this phrase ("I know not...") as opposed to a different one.

However, the advantage of this is the fact that such a phrase allows us to establish the time period of the story. From this, we can imply that the syntax belongs to an earlier time period.

free time is when all my homework and chores have been done for the day and i am "free" to do things that i enjoy doing.
