I think its great that you are ready and willing to expand your boundaries.

First ya have to say hi and make eye contact, a smile helps too.

Try to put a focus on asking and listening. When you hear something you feel or have experienced say something like " right? I feel/think/noticed it too"!.

It will get easier as you gain confidence in yourself. Choose your friends wisely though.

Good luck and let us know how it goes.
