The doctor, a younger man with neatly combed dark hair and thin square-rimmed glasses, asked about a few vaccines for diseases she hadn't heard of. Apparently humans could catch "chicken pox." She had nearly admitted that she had already gotten the pony pox when she was a filly, but caught herself before saying anything. Just how many species' diseases humans were susceptible to was still unclear. She had gotten a few needles stuck in the soft flesh of both arms. It was even more painful than getting shots as a pony.
