I'm at a loss of words, any suggestions?

Develop Scripts. One way to deal with "not knowing what to say" is to develop templates or scripts. Another thing you can do is create 5 to 7 questions you will ask another person when you meet, such as, "where did you grow up? " or "what do you do in your spare time"? If you focus on learning about the other person and get them to talk about themself, it takes the focus off you.
