Well, I'm learning. I added the hair command
delperson[figure= hair5_9EXP]
load [file= data/standard/skins/hair6_2EXP.htr]]
settexture [tex= data/standard/skins/blklngr.jpg]]
to sad.hap
I tell lois I love her, then respond again, lois becomes sad, she becomes a brunette!! And her clothes change.
It's not much, but a start.
