Back From A Dream World

So my vacation is over and the realization that I have to work for a living has set in.  As I sit here at work thinking about the fun I had over the past week and a half in a world that seemed void of all wordly concerns.  I am reminded that all the fun I had in that world comes with a definative price tag in this world.  Where once I was happy to find a meal consisting of a sandwich, soup, and 2 side items for 9 Euro(~$15) .  I now find myself passing on the larger meal because its an extra 50 cents on a $5 meal.  What has happened to that world and my mindset???  Is it because I am now burden with the task of earning my money again, where as I had forgotten the value of a dollar while I was away?  Who knows???  All I know is that the bills are in front of me again and so I must continue to work on like I have always done.
