I don't actually have any books that go along with this post. It's just something I sort of picked up over the course of many books. Most of my post will have books attached to them, it just so happens that this one doesn't.
Rules are supposed to be broken.
No, I don't mean laws or the type of rules that will get you thrown in jail and/or prison. No one wants that.
I'm mainly talking about the applied social rules. The ones that are like 'don't make friends with the weird people.' or 'don't touch that.' Many things that are not supposed to happen, happen in books... I know that most of the time it is actually a good idea not to touch a certain item if it is clearly indicated. But in books, its a fabulous idea that will change the course of the entire world as we know it!
(But please don't actually touch things that are off limits... They are off limits for a reason)
As for the weird people (No I have not forgotten about my people) you always want to at least have a conversation with some of them. I am not saying that you have to invite them to the movies or to a sleepover. All I'm trying to say is, talk to one of them... Get to know them personally.
A lot of them are some of the funniest people you will ever have the chance to get to know. I had a friend, her name was Savannah. Let me tell you she would make these quiet snide remarks that if you weren't close enough, you would never have heard. One time she made a very shady comment on a book we were reading, and the teacher overheard her and could not even fathom that it was quiet little shy Savannah.
All in all, most social norms that you come across, be it weird people or if it's don't let the outsider into the group, its always because people don't like change. Change is a necessity in all civilized society, it just takes a little bit of work and people as a whole are lazy. Be active. Be the change.
