Gekko, good list! I agree with R2C on the compliments. Avoid anything related to appearance or "sexiness". Compliment her on her work skills, or parenting skills, what a great friend she is to others, things like that.
Good- "That's awesome that you helped your friend with her daughter when she was sick, I bet she really appreciates having a great friend like you."
Bad- "Wow your boobs look huge in that!" ;-)
Thanks AS. In general I want to make W feel good about herself. I will focus on insightful compliments when the opportunity presents. No forced or contrived compliments, she will see right through them. And nothing about appearance unless she asks for an opinion.
