You probably have an email that you haven't read, this could be in Inbox, or Drafts.. it could also be a 'failed' text message that you need to delete or re-try to send...
Life is a tool, use it wisely and properly. Don't break it, because you can't exchange it if you do.
Life is an instrument, it needs regular cleaning, maintenance and tuning to keep it at its best.
Fear, is not knowing. Terror, is finding out.
