I go through my closet and find a new light bulb that will fit this lamp and place it in my pocket . I also get my stepladder and place it under the lamp . I climb up the ladder and unscrew the old light bulb . I place the old bulb in my pocket and take out the new one . I then screw in the new bulb . I then throw out the old bulb into the recycling bin . I go back to my bedroom and turn on the light switch . I am happy to see that there is again light in my room . Question: When did they climb down the stepladder and what did they do? Option1: to get the new lightbulb Option2: after they replaced the bulb, then they threw out the old one
