There was a time when I thought my dad didn’t know a thing about being a good father. I couldn’t   31 him ever saying the words “I love you.” It seems to me his only purpose in life was to say “__32_  ” to anywhere I wanted to go and anything I wanted to do, including getting a   33 .  Some parents bought their kids cars when they got their driver’s licenses. Not my dad ---- he said that I’d have to get a job and buy my own.
So that is what I did. I got a job at a very nice restaurant and   34  every penny I could and   35 I had enough to buy my car, I did! The day I brought that car home, my dad was the first one I wanted to   36  to. “Look, dad, a car of my own. If you ever want a ride, I’ll only   37 you five dollars.” I offered with a smile.
“I see,” was all he said.
One day, there was something wrong with my father’s truck. So he needed a   38 to work. . The sun wasn’t even up when we left the house,   39  it was already getting warm out. It was going to be a(n)   40 day. As I dropped my dad off, I   41  him, dressed in his work clothes, getting his   42  from the trunk of my car. Watching his sun-weathered face, and even from a distance I could tell there were   43  lines than I ever remembered being there before. I realized how hard my dad works for the family. My father is a cement finisher. In that instant, it   44 to me that he actually got down on his hands and knees to sweat over hot concrete to make a living for his family. And he did this day in and day out,   45  hot it got. Never, not once, had I heard him   46  about it. To him we were “worth” it. And never once did he “charge” us for it.
When he closed the trunk, his tools set off to the side, he walked over to my window to   47  me five dollars. I rolled down the window and said “Good-bye, dad. Keep your five dollars. It’s my   48. Don’t work too hard. I love you.” His   49 met mine, then glanced away in the direction of his waiting tools, he   50  his throat and said, “Oh, and… me, too.”
