I abstain from the consumption of animal products because i am a vegan and i don't think we should eat animals.  But i do love Mayonnaise.
Ah, out of curiosity did that start at a young age or did that happen in adulthood because of an event?
My parents are vegans too, we all follow the vegan philosophy. 
Is being a vegan hard?
not really, but there are different types of vegans:  "Dietary vegans", "ethical vegan" , and "environmental veganism". Which type would you like to know about?
What can you tell me about ethical vegans?
Ethical vegans not only follow a vegan diet, but also extend their philosophy into other areas of their lives, refusing to use animal products for any reason.
Oh, when did ethical veganism become a trend?
In the past.  The main take away is that a vegan diet can prevent some types of chronic disease, including heart disease, which is the number 1 killer.
Oh, I see. Is there anything else cool you can tell me about ethical veganism?
Even pregnant women and newborn infants can benefit from a vegan diet.
