Your friend sends you to scout Ziggy because she secretly has a crush on him. She told you to ask him if he would teach you to play the guitar (even though you can play it perfectly well). She decided that she would be ashamed to ask him about it because he would agree and see how she couldn't cope at all. She wanted you to find out as much as you could about him and then tell her. You asked Ziggy about „guitar lessons”and you have now arranged to meet at his house.

You knocked on the door.
