Not sure what you mean by side effect, but the perks of a good friend is someone to talk to, someone to help you with decisions, motivation, and keep you in check. But you have to return the favors too, you need to listen and help them like they do you. There shouldn't be any downsides, but each person is different.
I had a best friend for 17 years, but she was mouthy, couldn't keep a secret, and had to be the spotlight everything, But she helped me through breakups, failed adventures, and we had great times together. Each person is different with their ups and downs, and you will find out what those are with time.
A person who loves you no matter what and who you can never get rid of.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
