Deers flock  nicely with  other Deers

Cows share stables with other cows in great comfort

Horses gallop in the company of other horses

Idiotic and adamant people revel in the company of similar people

Men of wisdom seek the company of enlightened peers

Therefore,

sustained friendship can be kept only among people

with similar mindsets

and

placed in comparable environs

In fact so much of trouble in the society arises from flocking together donkeys, monkeys, horses and elephants all together..
