So, I'm curious.

As I'm sitting waiting for T, she walks out with the person who had the appointment time before me.

So I promptly hid behind a magazine and tried to make myself invisible.

Because T's immediately prior appointment....was with someone I was in the nut hut with a few weeks ago.

I didn't say anything to T, and I tried to stay out of sight till this person left, because I didn't know if she would want a reminder of that place.

What is proper etiquette in such situations? Do I say to T, "oh, I know one of your other clients"? Do I say hi to my fellow nutjob? I truly have no idea.
