Yeah thats how I would be.. although she has spoken at length about it with me, which I dont mind really but basically about how difficult it can be being vegan out and about, eating out etc and just generally running things past me, I never ever saw it as a way to try to make me feel guilty or convert me, it was just general chat about being vegan and I supported her and listened because thats what I do.. until very recently.
As you say, its like an ex smoker banging on and on.. noone is ever ready to make changes in their life when someone else is, its a personal time shift thing in themselves.
I am sure she will calm down in near future as she gets to grip with it all herself. I really love her as a friend and I wouldnt want to spoil the friendship... am also damn proud of her for making a very difficult change in her life, especially as she has four kids to juggle too..
I have days where I am vegetarian and dont eat meat.. so you could say I dip my toe in occasionally lol
