What do you say if a stranger asks what your imprint is?

I looked through the subreddit’s FAQ’s and didn’t see anything about this.I live in California and I’m considering going for my CCW.One thing I want to be sure I can handle is that question... “what’s that in your waistband?” The only response I could think of was “oh.. it’s my insulin pump”... but i don’t even really know where on the body those go.How do you answer that question without freaking people out? via /r/CCW http://bit.ly/2RaxYSu
