My sis... | has a problem

Yes. But you know how girls are at this age. Plus I don't think it should be such a big issue. I mean it's not in her nose or anything. It's not that visible. But the problem isn't what you think it is. If you ask me, my parents, as me, were more worried about the hygienical aspects, the safety of it all, considering that the respective "industry" here is quite undergroundish and unsafe.
