My dads reason is he dont want me to basicly have a ****** job. he wants the best for me which i can see that,Becuase he is helping me get ready for my EMT-B class and he is helping get ready to join the military and pursue my medical knowledge into the military so when i get out i have a better chance and high qualifying scores to get a job as a MA,A Doc,so on.. He thinks that all CNA's do is whipe "ASS" excuse my language. so ya he wont let me take CNA
