I grew up in a community called Estepona. I was 16 when one morning my Dad told me I could drive him into a 16 village called Mijas, on condition that I took the car in to be 17 at a nearby garage. I readily accepted. I drove Dad into Mijas, and 18 to pick him up at 4 p.m. then dropped off the car at the 19 . With several hours to spare, I went to a theater 20 , when the last movie finished, it was six. I was two hours late!
I knew Dad would be angry if he 21 I′d been watching movies. So I decided not to tell him the truth. When I 22 there I apologized for being late, and told him I′ d 23 as quickly as I could, but that the car had needed a major repairs. I′ll never forget the 24 he gave me. "I′m disappointed you 25 you have to lie to me, Jason." Dad looked at me again. "When you didn′t 26 , I called the garage to ask if there were any 27 , and they told me you hadn′t yet picked up the car." I felt 28 as I weakly told him the real reason. A 29 passed through Dad as he listened attentively. "I′m angry with 30 . I realize I′ve failed as a father. I′m going to walk home now and think seriously about 31 I′ve gone wrong all these years." "But Dad, it′s 18 miles!" My protests and apologies were 32 . Dad walked home that day. I drove behind him, 33 him all the way, but he walked silently.
Seeing Dad in so much 34 and emotional pain was my most painful experience. However, it was 35 the most successful lesson. I have never lied since.
