I was 16 then. I cut out the meat intake immediately. I happened to one day take a stroll in a part of the town where butcher shops were in plenty and I stood and observed the butchering process out of curiosity. Whatever I saw left me pale and horrified. I came back home and cried a lot. The shrieks and cries of the hen didn't leave my mind. And I decided from that day onwards that I wouldn't kill for my taste buds.
In the USA, it is not difficult to go your whole life eating meat and never seeing where it comes from, other than "from the supermarket refrigerated aisle." Many if not most supermarkets don't butcher on site (eg, in college I once briefly worked at a Walmart meat department and was disappointed I would not be learning any butchering, but would just be moving around boxes that happened to contain meat)
I'd like to propose a perhaps odd view: It may not be wrong to eat meat, but it's surely wrong to eat it if you wouldn't be willing to do the butchering and preparing yourself if that were the only way to get it.
