    It is interested to look at differences between schools in different countries. In many European countries which the relationship between teachers and students is quite formal, discipline and respect for the teacher is considered as very important. In northern European countries, however, the relationship between teachers and students are more relaxed and much friendly. In America, for example, the relationships are quite formal and the same is true of Britain. Other important difference is whether schools are state schools and private schools.
