Love for native country

There are a lot of kinds of love that people may feel. And in majority of cases the object of this love is a person, a child, a woman, a man, a parent etc. But of course sometimes people may also feel love to objects such as motherland.
The country, city and your house will always be the part of you and your memories. You'll always keep them in your heart and you'll always love them.
Psychologists explain that by the fact that people associate their homes and country with something similar and dear, with their childhood, first friends and the tenderness of their parents, that is why wherever you are you always feel the necessity to come home and you always miss your country when you are away.
Patriotism is a special term to name love for your native country. To protect and to save the native country is real patriotism. There are a lot of people who feel this love and are ready to sacrifice themselves but to save their country.
Till now psychologists and philosophers as well as scientists can't say exactly where patriotism appears from.
Some people say that this feeling appears from childhood as a person feels the connection with the place he was born in. Later school develops this feeling and teaches to love the country you live in.
Some people say that if a person doesn't love his/her motherland then this person doesn't love his/her mother. Love for native country is a necessary part of every person.
Sometimes when a person gets old, he/she begins to feel the necessity to visit his/her motherland. A person needs to unite with the country and his/her origins, so he/she misses the native country.
