If they are your old best friend then I find it hard as to why you don't like them any longer unless they feel there is more to your relationship (love). Either that or you haven't seen this person for a long while and you don't like what they have become. You don't tell them anything right off the bat.
Try to gently ease out of speaking with them on the phone, or meeting with them. If they call, don't answer the calls, and if they want to go out say you are busy. If they still don't get the message then you are going to have to really choose your words carefully so you don't hurt their feelings too badly.
You could say something like, "You know, after all this time I have come to realize that we have grown apart and we have different paths we need to take and it's time to move on." If nothing else works, then you are just going to have to tell them bluntly. Good luck Marcy Answer If you've been hurt or disappointed (or you've simply moved on for one reason or another), having distanced yourself should be enough to convey that you are no longer invested in this friendship.
If your friend SEEKS a reason for the distance that's grown between you, you can either give that person an honest account of what's upset the friendship (ie the cause of your withdrawal) or you can continue to politely distance yourself if you don't have the emotional capacity or desire to tackle what has upset the friendship.
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.
