Lol, Cupcake you are in a state of grace at the moment as I have never read it in either language, so I am more than happy to take your translation, its a lovely quote as it is, so I am happy to always let it stay that way with no further investigation necessary
As for the natural herding instinct, I agree its all within us to a lesser or greater degree. I think people approach cliques sometimes with the dear need to be 'part of something', or merely 'to belong', some may be desperate enough emotionally they are willing to hang in there until acceptance comes around. Some others just think 'stuff this for a game of soldiers I'm off' and really don't feel the need to want to bother.
I think its all kinds of things that motivate cliques and groups, loneliness, insecurity, displacement due to a new area etc, all of which you mentioned before. Nothing wrong with needing to belong, its a very comforting feeling, knowing people like you and like being with you.
I have a group of mums I stand with sometimes and I am happy to say they will talk or happily chat to anyone regardless. I guess I belong to that group, although as a group its very relaxed, sometimes we walk in together,sometimes only see each other fleetingly in passing and only manage a quick 'hi!', or not at all if the timing is off. Yet no-one feels aggrieved or shunned. Its just life and how it goes at times. I don't kind of consider it a clique as such, because anyone who is stood by adds a word or two to whatever is being said, they are then promptly included in the rest of the conversation if they so wish. Not at all how I have witnessed some of the other cliques of mums behave. They seem to veiw 'outsiders' the way a herd of deer watch a wolf making a pass by.
I won't purposely exclude someone if they are from the 'wrong side of town' type thing, I have been witness to those who do have that postcode snobbery, and as much as its amusing in its alien concept, it is actually pretty nasty in reality, I'd so hate to be like that and fall into the realms of being regarded as that shallow.
I don't know, its a very complex and emotive subject isn't it? I know I have been 'selective' who I spend my time with, and now I think back on it with a different take....was I excluding someone who needed something? I'd never be outright nasty or ignorant to anyone, but I do tend to keep a low profile with people I think either I won't like, or won't like me. In retrospect, did I not give them enough of a chance? Hmmm, bit of food for thought for me there I think.
