I consider myself 95% Vegan, since I still eat (ocasionally) some products containing milk and/or eggs, specially at birthday parties (friends and colleagues' birthday cakes, for instance), otherwise I wouldn't socialize at all (one of the few concessions that I still make to my daily regimen). I also have to suspend my vegan principles whenever there's the need to take drugs and/or vaccines, which unfortunately still use animal products (like lactose) or are tested in animals. :( I hope this will change in the near future though. :)
