What does at diplomat do?

Diplomats represent their government. They could also be posted in Another Country,maybe 3 or 4 years and a diplomat and his/her family would get a diplomatic passport,so when the diplomat is posted in another country, they won't have to pay for the flight. Oh, and the diplomat's parents would also get a special passport, so that they could go for free too and i think the diplomat's children would get free education,when they're out of their country. Believe me, i'm a diplomat's daughter and i would also want to be one.
