"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.
"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.
