Have it ever happened to you? Have you ever closed the door and then remembered there was something you had left.When you left home again,armed with the things you need,did you find the time was late for work?  The careless people always do like this.A recent case conserns Jane,my classmate in the accounting class on weekend.One day,Jane got up early and had a wonderful brekfast.Then,she left home and without realizing it, dressed in her night-suit.Imagine her dismay,when she realized this.She at once went back home and changed on her smart red skirt.Looking at her watch,it was nearly 9 o'clock.She must be late again.
