When I started I used to plan what I wanted to talk about. Sometimes I would email him points that I wanted to cover the night before so I wouldn't forget. Now I go in with no plan. I sometimes have stuff to say and sometimes I don't. I see him twice a week, so sometimes I don't always fill both sessions with talking. Thankfully we go for walks on both sessions so even if we aren't talking we are walking together its not an awkward silence. Sometimes a lot is said in silence.
