The friendly is a term in common use in our language when we want to express respect to someone who is pleasant and attentive in their interaction and dealings with persons with which it is linked. Then, when an individual behaves with sympathy, with good manners and much cordiality say it is friendly. Meanwhile, the kind word is closely linked with the concept of friendliness that comes into the State behave so benevolent, friendly and great charity with those individuals with whom it interacts. Who is naturally friendly always is willing to lend a hand you need to and if for example you see an older lady that is to cross the street with difficulty, immediately, stop what you are doing and run to help you at the crossroads.
Notably, that kindness can be always present in the way of being a person and therefore always will be conducted and will be guided by this, though, kindness can also appear occasionally in the mode of behaving someone as a result of complying with the socially accepted and expected of people while they live in community, and also someone may feign kindness with a mission to meet or achieve a particular goal or purpose. In the latter case the kindness will not be a pure quality, but it will be grandiose.
Elsewhere and its linkage with the courteous, attention and service is the kind word is used in our language as an indicator of courtesy when it comes to requiring any question, asked. It is so common that we find the following expression: "could be so kind to serve me less milk than coffee, thank you".
The absolutely opposite of what kind is it rude, the gross, the unpleasant and unfriendly, so when you want to express the opposite of friendly is usual that use any of these words.
