Cliques. What are they?
It gives an identity to a group of people. It splits the good, bad, physical, musical, crazy, quiet, intelligent, morons and whatever types of people you can think off. Some cliques are mixtures of the above. It also strengthens the bonds between you and the fellow clique members. In the clique, you can usually seek help from fellow members, and they should be willing to. Having cliques is also a way to know each other better. It's also fun having them. Sometimes you have different roles in a clique, like a mafia gang does.
It also separates you more from the outside world. Usually, more of your time will be spent with the clique, than the people walking pass you. It is hard to balance time with friends outside and the clique. Everyone in the clique is important. Usually, if one step or more step out of it, it gets disbanded. That's why sometimes its a short-term thing. At times, They will disband, regroup, disband and regroup again and again.
If you think you can overcome the above, then having cliques is not a problem. If not, then either make changes or stay the way you are. Anyway, who am I to say this? I don't make the rules. Still, it's just what I myself personally thinks, and this is my blog, so I type with no law.

Well, it's been boring. Lessons and more lessons. I type about something more interesting next time, I think.
