I have found that the one thing that causes me to go out of my routine is someone coming up to talk to me while I am in the middle of my routine. Your'e leaving so you are glad to see them to be able to say goodbye. Don't get mad or chase them away they are your'e friends. Don't just go back to where you left off, that is how things get missed. (Where was I.) Start all over like you hadn't even started yet. That is the only way to make sure everything get done properly.
