Anyone that age, who has cooked for that long, should know alfredo has dairy in it. And EVERYONE knows alfredo sauce is fattening!! even people who don't have IBS!! And they were "cut to the core"? Geez!! How are you going to deal with this? Actually, I'd say it's your husbands job to talk to them, why is he still being a jerk? Does he think you overeacted?
