Yesterday, Patrick had been told that his documents needs to be verified by the end of the week or his trip would be called (7) .

At first the line was engaged but when he eventually heard his mother’s voice, Patrick was greatly relieved. “Don’t you remember? You left your passport (10) with me after your last holiday in case you lost it.”
