Moving into new cities? For some people it is good experience

For tons of years I was living in only 1 city. Actually, this was the same one where I was born, where I made first colleagues, went to first school, in which I met my first sweethearth et cetera. This small city where I grew up was for me the whole word. At that time I possibly wasn’t even able to imagine any other place. Honestly speaking, I didn’t even think that they exist. Obviously, I was seeing them in television and so on. Unfortunately, they seemed to be so unrealistic that they were more abstract, therefore didn’t even seem to me like to be actual places.
