My mother swears that I liked meat when I was little, but I don't remember and so I don't entirely believe her. Because the first I remember, when I was 6, I suddenly hated the taste of all meat (a distaste that extends to most animal products, though I'm not officially vegan because i can't give up cheese or ice cream) and refused to eat it. I'm one of the lucky ones whose mother actually let her become veggie at that age.
This was 14 years ago, before being vegetarian really came into vogue, and man was I glad when it did! When I was about 10, I remember going on a trip with my family where we ate out for every meal. I had Ceasar salads for dinner six days in a row, because it was the only option any of the restaurants had for me where I could at least tell them not to put bacon on it. Then, all of a sudden, all of the restaurants and grocery stores started carrying options for vegetarians, and there was actually real food for me to eat!
It's interesting for me because I've gotten pretty much all of the reactions to vegetarians by now, and they have definitely changed over the years. A lot of people used to act like I was some kind of freak, and some even told my parents that they should force feed me or I would turn out to be weak and wimpy (I still have not seen this happen to any vegetarian!). Nowadays, vegetarianism is so mainstream that no one is even surprised when I tell them, and most of my friends either are vegetarian or have tried it. What I get most now is people who assume that I am an animal rights activist, which I'm really not, just because that's not really my area of interest. I have opinions about it but they're not particularly vivid forces in my life. Since I've been vegetarian for so long, I kind of bypassed that phase, because I was vegetarian anyway, so why pay attention to campaigns trying to make people become veggie?
Only problem is, I didn't do vegetarianism properly when I was younger, didn't get enough protein, and ended up slightly stunting my growth, so I am significantly shorter than all of my siblings, which is somewhat frustrating!
. So my advice to any newer veggies is that if you're going to do it, do it right, because you really only get one shot with your body.
