People and numbers

There are Schools don’t have any names in Russia, but they have numbers. For example, I teach in the thirteenth school.
As a rule, if somebody gets to know that you are a teacher, he or she(they will ask or they'll ask) asks about the number of your school. To tell (you) the truth, I don’t understand why. There are 196 schools in Kazan, so I can could say any number under 196, because that man couldn't  but someone couldn't possibly know about all the schools there.
Also, I don’t understand what he or she (they want) wants to get know about me?  Do they feel differently about  the teachers, who work in deferent different schools? I think, only an expert can do it, because ordinary people usually haven’t got (don't have....is better)  this information.
As for me, I teach in a “Night School” for juvenile offenders and I don’t keep back hide the number of my school (from anyone who asks), but people never understand that my school is unusual. They hold are in the firm belief, that I’m a really good woman(person).
Perhaps,  knowing numbers makes humans calmer  makes people feel better about certain things.

There are schools don’t have any names in Russia, but they have numbers. For example, I teach in thirteenth School No. 13. ('school number thirteen')
As a rule, if somebody gets to know (finds out) that you are the teacher, he or she asks about the number of your school (asks you what your school's number is). To tell you the truth, I don’t understand why. There are 196 schools in Kazan, so I can say (give) every (any) number under 196, because that man (the person who is asking) can’t know about all the schools there.
Also, I don’t understand what he or she wants to get know about me? Does He or she feel different between about the teachers who work in deferent schools? I think, only an expert can do it (do what?), because ordinary people usually haven’t got this information.
