I feel so lonely in the city.
Why isn't it a lonely city?
A lot of things happen in a city, so many things to do but I am never involved.
If you are feeling lonely it is good to go out and make friends. If being lonely bothers you, then you should try to join a club.
It's a lonely city because no one wants me around.
That's not true that no one wants you around and if you avoid making friends then you will be lonely but it will be on you. Plenty of people would love to spend time with you, but you must meet them half way.
