"How's the vegan thing going?"

"Are you still a vegan?"

To me these question sounds a lot like Sarah Palin's recent speech asking, "How's that hopey, changey stuff working out for ya?"

I'm sure some people mean well, but I sense sarcasm and/or cynicism in there sometimes. And both being vegan and the hopey-changey stuff are working out very well, thank you.

Lately I've been answering in the simplest terms possible.
"For life."
"Forever."
"Love it."
"Fantastic."
"Great."
"Never felt better."

And to those being sarcastic, I always see a look of surprise at the confidence in my answer. It's like they expected me to say:
"Man, this vegan thing sucks. I had to eat a burger the other night cause I'm so weak. It's really hard. I'm not sure anymore. I'm changing my mind."

And then there's usually no follow-up besides "Really? Wow. Alright, see ya later."

I handle it like the mature adult that I am. I don't get upset. So to the sarcastic nay-sayers I say:
In your face.
