Are you truly vegetarian?

I was searching for the term ‘Vegetarian’ in Wikipedia, the free encyclopaedia in WWW, I found out that vegetarian is actually divided into 4 common types:

• Lacto-ovo vegetarianism is a diet of only vegetables, Eggs, Dairy and Honey.
• Lacto vegetarianism is a diet of only vegetables, Dairy and Honey
• Ovo vegetarianism is a diet of only vegetables, Eggs, and Honey
• Veganism is a diet of only vegetables.
