Imagine you are going on a journey. What things do you need to do get ready for your trip? If you are going for awhile, you have to go to the post office and stop your mail. You have to stop the newspaper and maybe some other regular deliveries from coming to your house. You might tell your trusted neighbours you are going away and have them watch the house for you. If you are a pet owner, you have to take your animals to the kennel. Then there is getting documents together for your trip, making sure your bills are paid, packing and all those sort of things. At work, you need to get everything ready so that things might go smoothly in your absence. And this is all before you get in the car or get on the plane.
