I was a vegan for a whole summer once. Have you ever done an alternative diet like that?
No I have not, what is vegan?
A vegan is a person who does not eat meat or any other animal products, like dairy or eggs. 
Wow, I like steak too much to be a vegan.
Well some people eat vegan because they have moral feelings, but I just wanted to try it. Personally, I love chicken over steak.
