["I'm going to drive a truck. Never driven a car that big before.", "I'm sorry, but I don't envy you... I've always just driven a little sedan. I'm an alright driver, but if I had to drive something bigger, I'd be nervous, too. Too easy for me to make mistakes. I kind of dread the day where I'll have to drive a big Uhaul truck. I hope things go well for you, though.", "Thank you so much. I hope with time I'll be okay with it. For now, I'm kinda scared."]
Well, as long as you're patient and careful, you'll minimize your mistakes. There are those who go out there and think they know everything. Even if they're a good driver, they may be more likely to slip up and have a problem than you would. So, just stay positive!
