yes, I am extremely diligent with gluten, to the point where it certainly seems like paranoia to an outsider; expressing such behaviors as not using paper towels if the roll was sitting on somewhere with crumbs (could be on the edges) to using a paper towel to hold around the remote (a popular spot for those non-gluten-free'ers in my house to snack)
I also shy away from close contact when eating, and freak out if someone waves their hand above my plate. (or anything for that matter)
Also wash out pretty much every bowl/utensil before I use them (even if they are already 'clean')..
Not really worth the risk.
