Is there really such a thing as spying?

my name is john. but I have another name. another name is used to spy active. It is what is called a code name. The general public will have a chance to hear it often in movies. That's what I use in real life. People may long for me to say such a thing. But the reality is more difficult than the ideal. The work is stressful, mundane , risky and hard. Then some may question why I started this business. The reason is simple . I wanted to work for my country . And I had talent. I started this job with such pure feelings, but now I am not that enthusiastic about it . Nevertheless, this work must continue for the rest of my life. And then they find themselves in a foreign country , falling in love and living happily ever after. We hear such stories all the time, but is it really possible? If you are a showoff, you might brag about being a spy.
