I once got the "what's that?" from the wife of a friend of mine when she noticed my Omnipod for the first time. She knew I had diabetes, but had little understanding of what that meant, nor any desire to understand what that meant. After I explained what it does and what its for, I got the "Eeeeeww, gross - I could never do that." "Yes, you could, I responded, if that's what keeps you alive."
