Raised in a fatherless home,my father was extremely tightfisted towards us children. His attitude didn't soften as I grew into adulthood and went to college. I had to ride the bus whenever I came home. Though the bus stopped about two miles from home,Dad never met me,even in severe weather. If I _ he'd say in his loudest father-voice,"That's what your legs are for!" The walk didn't bother me as much as the fear of walking alone along the highway and country roads. I also felt less than valued that my father didn't seem concerned about my safety. But that feeling was canceled one spring evening. It had been a particularly difficult week at college after long hours in labs. I longed for home. When the bus reached the stop,I stepped off and dragged my suitcase to begin the long journey home. A row of hedge edged the driveway that climbed the hill to our house. Once I had turned off the highway to start the last lap of my journey,I always had a sense of relief to see the hedge because it meant that I was almost home. On that particular evening,the hedge had just come into view when I saw something gray moving along the top of the hedge,moving toward the house. Upon closer observation,I realized it was the top of my father's head. Then I knew,each time I'd come home,he had stood behind the hedge,watching,until he knew I had arrived safely. I swallowed hard against the tears. He did care,after all. On later visits,that spot of gray became my watchtower. I could hardly wait until I was close enough to watch for its secret movement above the greenery. Upon reaching home,I would find my father sitting innocently in his chair. "So!
