Of course you teach kids. Every single minute every single day, more by the behaviors you display than the words you say. Around here that includes NOT making judgements on the mom that comes to school every day for lunch, the dad that has yet to show for even one single school function and the parents that throw their kid a $10,000 party for Bday #7 (because 7 is their favorite number).
When we see someone that does things different than we do, it's a teaching opportunity.
EDIT to add when you quoted me you left off the part about having morals standards AND an open mind...that was the key to that sentance.
I just thought the question was, "Would we do it?"
If DD had asked me to bring in treats just for her girlfriends, I would have said, "No, that would hurt too many other kids' feelings". It's not like we sat around cattily criticizing other girls and their moms, but I guess she knew I didn't approve because of what I would and wouldn't let her do.

) We just don't need that stuff and we shouldn't be teaching it to our girls.
I will sometimes go have lunch with my DH at work. So it's not beyond the realm of "reality".
