I love that there are many scenarios that are practical & useful etc. but maybe it’d be good to inject a little bit of humour into the sentences from time to time. “How long have you worked here” and “We went to the cinema” yesterday get boring after awhile.
Your advertising had a lot of clever & fun phrases, it’d be cool to add that into some of the sentences from time to time, to keep the energy up when doing flashcards & scenarios.
