My dads job

My dad got this really good job over the summer last year. He loves being a truck driver. He enjoys the money, and the guys he works with. My mom doesn't like it so much. Because my dad lately hasn't been home every night. And he has started to work on weekends sometimes. But that is because of the weather. My mom understands that she can't change his mind about his love for the job. But it's starting to worry me now. There has been more semi wrecks around the surrounding counties. I hear a lot about what is going on out there from my dad. And i'm worrying that my dad will be next. He keeps having problems with the semi. And he can fall asleep real easily any more. My mom thinks it's that sleep apathy thing. I'm just worrying because he has already been in one wreck since he got this job. And i could have lost him if he didn't have his seat belt on. But there is always that possibilty that the next time he won't survive....
