Before you start to judge me, step into my shoes and walk the life I'm living and if you get as far as I am, just maybe you will see how strong I really am - Unknown
Well, you see, it's not that hard to understand apostrophes. It's just a punctuation mark to indicate possession. Though, don't assume that I'm Shinichi's possession, just because I'm shinichi'sapprentice. The apostrophe in shinichi'sapprentice is just there for no reason whatsoever. xD Good luck anyway!
