After graduating from colleges I was able to find a job and move
out of my parents' home.When I had fixed up the place a liitle,I
proudly invited my parents to come over to see my apartment for
the first time.To my suprise,the first thing my father did upon
arriving was to go to every room and turn on all lights.
When I asked him why he answered with a smile,"I've
waited all my life to get back at you for always leaving the lights
on at our house."
