It is one thing to rag on students for wearing fake nails (which is understandable, it IS a major infection risk), but the whole ragging on students wearing many earrings or having tattoos is incredibly WRONG. We cannot UNDO our piercings and tattoos. But I guess this depends on this school's policy. At my school, they say we can wear stud earrings, but they do not tell us to hide tattoos. It depends on your policy. If your school's policy specifically limits the number of earrings or the revealing of tattoos, I would abide by it. Anyhow, this email could have been a little less rude.
