Time to say goodbye

Whatever you think you know, you don't know and whatever you guess, is wrong or exactly right.

 But unless you are a complete idiot, you will always know when the genuine friendship you once had is gone to be replaced with a barely concealed tolerance.

 Then you know to extract yourself and be swift, be thorough and be final.

Goodbye you say, cheerio, see ya.

Make no drama, take a pledge, and closed the door, lock it and throw the key with great force into the sea.

Bye
