The more I spend helping adults improve their English, the more I realise that standard book syllabus is not essential. Just deal with needs as they come up. Dealing with their own mistakes and questions feels a lot more rewarding to them than sticking to a carefully planned lesson. Most just want a sympathetic teacher or native speaker to identify and notice words and expressions from and to listen to.
Now that I am planning to overcome a fear and I'll be paying someone to help me, I realise that that's what I a doing with my students.
