I know peta2 has pointed this out before and encouraged people to change it but I wanted to point it out again because I am having to much fun adding random events to my own timeline right now lol.
If you go on your facebook profile or timeline (not your news feed!) right where you can post statuses click Life Event > Health & Wellness > New Eating Habits… > Then you can choose between vegetarian, vegan, pescetarian, fruitarian, omnivore, or other. You can also add “Location”, “Who With”, “When”, “Story”, and “Photos”!
This is a great way to tell all of your fb friends you are veg*n (or even more people if you choose the public option), why and since when etc as well.
