Title: Fix File.exist? example

If `File.exist? '../event_attendees.csv'` is called with out the prefix `../` it will silently fail if the student wraps the `File.readlines '../event_attendees'` call in an `if..` block. This could, from experience, cause some frustration to a naive student.

Also correct typo on line 67, director for directory.
