|"Don't do nothing because you can't do everything. Do something. Do anything!"
I decided to go veg when I was 13. For me it just felt natural, I never felt like I was giving anything up. I also didn't just stop everything all at once. First I stopped pork cause I thought it was gross, then beef, then chicken/turkey and then I stopped eating anything with meat additives (boullion, etc). I definitely had a crappy diet initially, consisting of chips, pbj, french fries, mac and cheese, etc. My Mom sort of humored me because she thought it was a phase.
Well, this phase has lasted almost 30 years now.
I've never been much of an egg eater, they always kind of grossed me out nor did I drink much milk but it took me until about 3 years ago to cut out most dairy and eggs from my diet. (Cheese is the one thing I do miss.) What finally did it for me (and turned my husband veg) was watching the movie "Peaceable Kingdom"
So, we eat vegan at home but I don't consider myself a vegan because when we're out at a restaurant I do my best to get something vegan but if my 5 yr old really wants something with dairy/eggs or there's really no good alternative I'll get something for us with dairy/eggs. Or, I find that friends/family are really stumped with how to make vegan food so I don't make a big deal about eating dairy/eggs when visiting. For me, it's not black and white, I do my best but definitely something is better than nothing.
At any rate, my Mom and Stepdad as well as other people in my life definitely teased me about it (still do sometimes). What I figured out was that if I didn't get riled up about it, if I just laughed along with them, the teasing pretty much stopped. I think a lot of times people tease because vegetarianism makes them feel uncomfortable. Like they really don't want to examine their food choices too closely so to make themselves feel better they make fun of yours. I'm not a "preachy" vegetarian so I'm always a little shocked when someone lays into me about vegetarianism but I just chalk it up to their own issues/discomfort and just let it roll right off my back.
