Sometimes it is very nice to take some time out to just relax and be alone. I find that time few and far between but look forward to those times. It is nice when you have no worries of some decision you making affecting someone else besides you. It is great to just relax with a book or with a puzzle and just plain zone out for a time. Heck even walking around the mall without having to worry about meeting someone at this time or at that place can be relaxing.
I am glad that you had some important "me" time.
