Estragon seems to have a faulty memory, forgetting things that happened the previous day, or not remembering that they are waiting for Godot. Anything that is not currently happening is not important to him.
Don't chase someone who won't chase after you. Don't give to someone who doesn't appreciate you. NEVER push a loyal person to the point they no longer care. It takes work to get a person to that point and once there . It's hard to repair the damage
