I've only been a vegetarian for 4 months. [nobody thought i'd last longer than 2 weeks] and my parents were all for it. now i've decided to go vegan and my parents not only refuse to by the vegan substitutions i need, my mom flat out laughed and said it was silly. we're not talking about strict church going rule following people here, we're talking about my parents, the open-minded libral, accepting of most anyone kind of people. so this sudden closed minded way of thinking was a surprise. any suggestions on convincing them this isn't a waste of time?
