I'm giving a Greek lady conversation lessons, she's in her late forties and reads English at a good level and her grammar is fine for intermediate level. She owns a hotel and over the summer we based our lessons on the hotel, guests and activities in our area. The last few lessons I have tried to broaden this, as she has said she wishes to increase her vocab and speaking level, but she is unwilling to read or write. I would like suggestions to increase her vocabulary, bearing in mind she is pretty busy and i feel games etc. are unsuitable for her, and i'm sure she just expects me to teach her vocab without any innovative ideas, I tried some hypothetical questions but she couldn't grasp the concept and just wanted to relate everything to her guests and the hotel!
