I see 5 groups of girls sitting on the table and they were talking about stuff. So I decided to go walk towards them and talk to them. They all know my name and they all happy and smiling at me. Everything was going smooth until I freeze up on what topic I want to have in this conversation. I was kinda distracted in the group and they ended up talking something else. They seem to be losing interest in me just a lilltle bit. Then I told them I have to go do my homework.

I want to be a leader and take control of the conversation but I just can't think of a topic I want to have in conversation. how can I do this?
