I almost got my little brother and myself in an accident today
Wow! can you explain what happened?
I almost killed my brother with my car by playing with the gas pedal.
Cars are dangerous and so is being on the road. You should always be careful you could get hurt or you could hurt others.
Pfft. I don't care, it's not like anyone got hurt.
Still just because you avoided an accident today doesn't mean you might have the same luck next time. If you think you need to improve your driving skills you can take classes at a highschool or a private instructor.
