Congrats on saying NO to meat...
Yes it is hard to explain to most meat eaters why you don't eat meat anymore, most just don't get it and never will, the ones that have a lot to say about meat and how good it tastes are a waste of breath I have found! it does not matter what answer you give them they will always find a way to keep being critical of your decision to try and make themselves feel better.
I have now learnt to live with it and I just don't hang out with the friends or anyone that are for ever trying to prove how much Im missing by not eating meat.
I became vegan in March 2011

30 Day Vegan challenge never looked back, went cold turkey as they would say
No Murder, No Dairy, No Wool, No Leather
