When I told my family I was going veg, they thought i was going crazy..my mum even started calling me vegetable for a while! :)
You're probably thinking about how hard it will be for you to be the only vegetarian in your family, but trust me, it really is NOT THAT HARD!
People will always have an opinion on your choice that they feel they must express but if you don't take things too seriously you'll learn to brush away stupid comments.
Here are some things that my friends and family have said, you might be able to relate:
"You do know that animals don't have a soul right?"
"Don't you miss chicken wings and spare ribs and sausages?"
"God made animals for us to eat and do whatever we want with"
"You're not really making a difference, animals will still get killed!"
"You're going to die of hunger"
"Where are you going to get your protein from? You're going to stay the same height forever"
"Are you sure that's possible?"
"If you don't eat the cows, they're going to keep farting which causes global warming!"
And there are dozens more!
What I'm trying to say is, people can be REALLY unsuportive at times, and it's easy to tell yourself that they're right, but whenever you're thinking about caving in just because of other people think, remember the reason why YOU chose to change.
One of the reasons why I changed?
