vegan butter substitute for cookie baking?

2. Just curious why they (the just turned vegans) don't bring their stuff w/ them? Not everyone is...

educated or knowledgeable enough to determine what's proper or not for a vegan, and IMHO (me only), I don't have enough time to really worry too much about their eating habits, due to the fact that I'm going to be too busy fixing everything.

I've had friends that are vegan, and/or diabetic too, that did just this (bring their own foods), so this was very considerate of them and helpful to me as the host (too much going on of course taking care of everything in preparation for the dinner/cocktails/party/etc.). Also, the vegan guests have ensured that they are consuming what they know is safe food(s).
