Imagine you have lost your job and you couldn't pay the bills of your house. You decided to sell it and move to your parent't house until you got a new job. One day you were packing your stuff when suddenly the phone rang. It was your dad who had just seen an advertisement of a job. You had the ability to apply for it so you called the company and the boss said you had to go to a conversation with your CV in an hour. You put down the phone, got dressed well and were ready to leave but found the door locked and the keys were missing probably amongst the boxes somewhere.
