1. I agree with the way words are graded. Just to say something, maybe I’ll change wardrobe and I’ll teach it in a beginner level.
1. If I had to add 5 other words at each level. A possibility could be:
(i) Beginner level: bookcase, room, table, desk, mirror, shelf, lamp
(ii) Intermediate level: cupboard, sink, rug, carpet, fireplace
(iii) Advanced level: beam, trellis, hinge, dormer, hamper
2. It was a long time ago. I can’t remember exactly when. I travelled to Germany alone because I was going to attend a German course. I could barely speak German and when I arrived at Basel airport my suitcase wasn’t there. I was lost. I didn’t know what to do. I claimed about my luggage and they told me they were going to send it to Freiburg, where I was staying in. The problem was that I still didn’t know my address. So they couldn’t send it to anywhere.
I cannot remember exactly why but I just kept saying “Mein Koffer ist verloren”. I was without my suitcase for 2 or 3 days, of course the flight company gave me money to buy some clothes.
