My last bus leaves at ten o'clock, so I'd better go home now. Christine doesn't look well - we'd better take her to the hospital. We don't have much food, so I think we'd better go and do some shopping. You'd better take a taxi because it's not safe to walk in this area at night. Jola's not usually late – I'd better give her a call. If you want to finish today, I think you'd better start now.
