It is not odd at all. One of my girls also seems to be hairy. Someone ethnic groups tend to have "hairy" arms and legs. The hair on my daughter's legs, arms and back stand out more because she is very light-skinned. She is half Mexican and that is how my husband's family is. As she has gotten older, the hair has thinned quite a bit. She is by no means hairy on her back but she does notice and sometimes says she hates the hair on her arms. I just try not to let it bring her down. I think there are enough problems out there for her to face.
BTW, I went to school with a girl who was 3/4 Italian. She was proud of the hair on her arms.
