Tell each other one of many "The first time I..."
So many first times we have.
The first times are scary.
The first times are joy.
The first times are funny.
We have many interesting first time to reveal to each other and at the same time we forget to fear to speak in public and show some from ourselves. My experience tells me that either prepared in advance, or challenged add hoc, that makes a great experience.
And, at the end, each is convinced: personal stories work!
