IDs=Pointless or a life saver?

I know, I know, you hate them.
But why?
I mean, is it really that much of a difference whether you have them or not? Oh no! They messed up your outfit. Now it's not color coded. I'm so sorry...
Seriously???!!! Come on.
Personally, I couldn't care less. I know what the school is trying to do. But not every teacher checks if you have them, and when they do, it's not as if they look to see if it is your picture. Anyone can take a friend's spare so they don't get a detention.
That's another thing: the punishment for having them is argued about all the time too.
A detention is not that long, and if you were a good student, you'd only be doing homework at home instead of school. So technically, this is a good thing. You have more silence so you can do your homework.
Of course, you need them to buy lunch, right? Not necessarily. You can just type the code.
So wait a minute, you don't need them to get into school, or for lunch, what do we need them for?
The library.
But only to take out a book.
Anyone can just take a book from the library, it's not like anyone is watching(just saying).
So what have we learned?
The IDs are a good idea that people will know who you are, but the teachers should know if there is a strange man in the back of the classroom with out having to check to see if he has an ID.
It doesn't matter.
Just where them and get over yourself.
It's not that bad.
Be happy for the things you have instead of complaining about the small things.
