A good bacon buttie can turn any veggie
Sadly, that did it for me. My lodger had bacon sarnies every Saturday morning (a man of habit he was) and I would sit by the kitchen door with my cats, drooling. In the end I snapped and 14 years of veggie-dom went out the window.
The good side of eating everything: I no longer have to lug carrier bags of food around with me (I was hungry all the time no matter how much I put away).
There are frequently periods of several days when we don't eat meat but we will a few times a week. Ironically, I might only have a bacon sarnie once every month… if that!
People choose to be veggies for a variety of reasons, some for very personal reasons, some for more political reasons. A lot of people chose to become veggies in the past on animal welfare grounds, however you can't change the game by not playing, so the same people might now choose instead to buy well cared for meat.
I worked in a chicken factory as a summer job and that put me off meat big time. It certainly wasn't very pleasant.
