I know people who are always pushing food too. I think it is part of the "if everyone is doing it, it's okay" mentality. That is one advantage of the gluten free diet, absolutely no cheating is acceptable. I will, in fact, suffer for weeks if I get just a few crumbs of gluten. I rarely eat anything at someone else's home. Because of the risk of cross contamination it's just not safe. If someone gets upset, they are not really a friend and I'm better off without them in my life.
