I wouldn't have a problem with it at all. Driving a school bus can sometimes be a thankless job. Drivers don't take the necessary training for the job and get up at the crack of dawn just to get close to young girls. They do it because they're committed to doing a good job and making an honest living. Don't forget that they've been fingerprinted and had their backgrounds checked, just as all school employees do. Sure, there are bad apples in every profession, but I wouldn't automatically be nervous about a male bus driver. Plus, at 12 1/2, your daughter is old enough to speak up if something is wrong or makes her uncomfortable.
