If we already have seen each other this week, he will usually ask how the time after last session/contact was. If we haven't seen each other the whole week, he'll start with "Tell me about your week" or "And, how about you?"If I decide to make small talk for a bit, he'll join in and ask what I would like to talk about today if I waste too much time. Otherwise, we talk about whatever I want straight away (which is what usually happens for me).
