Changing teachers

James recently changed his Czech language teacher, because the first one lived a long way away and, due to her other job, had little time to meet up. He was quite sad to see the other go, but managed to find a new one. Last week though during his lesson, his new teacher told him that she no longer has time to meet up with him because she has to go to Prague regularly for her course. But she then told him that his new teacher was coming in a moment to talk over the practicalities of when to meet up. So he managed to change teachers twice in a month. Somewhat confusing is that the second and third teachers are both called Suzanna!
