I'm glad the vet is coming. But something for you to keep in mind is that you (and your parents) are responsible for getting your horse seen by a vet if there is a problem. And your BO has no say in whether or not you can have a vet out for your horse. Legally and ethically as the owners the care of your horse falls squarely on your shoulders.
Just FYI since I've seen the same sort of "I have to ask my BO if I can have the vet out" comments several times lately.
