I start my first case tomorrow, pairing advice?

Hi, I just finished my competency exam and passed today. I feel really confident about my skills when it comes to things like DTT/prompting/reinforcement. However, I feel nervous to start pairing with my new and first client tomorrow. I am an introverted person and I can be awkward around new people. I know pairing involves limiting demands, being fun, and finding out their interests and things they like but I would like to know what your guy’s specific experiences with pairing are like especially if you can initially be shy. I’m sorry if a thread like this has been made before, I am not really tech savvy.
