Question Socials in Triggers

I've never noticed this before. Are mobs not allowed to use socials or is there a special syntax? Lines like "smile %actor%" don't hit. And now that I've noticed, I don't see any instances in the stock areas in a casual search.

Okay, this was my error. I got carried away with %send% %actor%s and used the same syntax for socials instead of <social> %actor.name%. This is probably why I never noticed socials not working before

If I had searched for "smile %actor" instead of "smile %actor%" I'd have caught it.
