Are you shy? So am I

I'm a really shy person.
How shy?
Well, for example:  at a recent writer's convention a group of us who had graduated from a grad writing program decided to get together for dinner.

We set up a place in the hotel to meet.
When I arrived there, another group waiting there asked me to take their picture beside the flower cart bicycle.  Which I did.  Then I sat down to wait.
The other group chatted together for a while.
Finally I texted the group I was supposed to meet --
and the chatting group turned to me --
they were the group I was supposed to have dinner with.
Oh.
I had been to shy to ask them if they were waiting for someone.
Since they were from different graduating classes, they didn't know me by sight and I didn't know them.
If only I were brave enough to simply join a group and talk to them.
But I'm not.
I'm shy.
