Haha. I remember that point. The whole "how the hell does this oo thing work?". Just keep at it, at some point it just clicks. It really is like a lightbulb going on. One moment it doesn't really make sense and then a split second later you're coding everything up in classes.
Try downloading some of the open source tools you will likely end up using and read the code. It'll give you something to reference your code style against.
