I often get a surprised look when my local skating friends first find out I'm vegetarian. The first question would be "where do you get your energy from?". The next question is, "then... where can we go to eat?".
Eating out poses some restrictions, but most of my friends are adapting and look for places where I can find something to eat. Over the years, my DH and I have set up a blog, Vegetarian Dining, about our experiences as vegetarians in Singapore and also as we travel around the wold.
Some years ago, I had a coach who disliked eating with me - not because of the restrictions on where to eat but because he didn't like the thought of me not eating meat!
So... if a person who eats vegetables is called a vegetarian, shouldn't a person who eats humans be called a humanitarian?
