Not everyone is entirely supportive of a gluten free diet. Oh, you know this, I know you do! Watch out for these people, who act as speed bumps on your gluten free path:
The food pusher - Anyone who has ever been on a diet can recognize these people. "Oh just a little won't hurt!" "Come on, I made it special for you!" Be polite. Be strong. Understand that they may feel insulted that you won't eat their food, but like breaking up with boyfriend, it's best to be honest, "It's not you, it's your gluten. But we can still be friends!"
The food hider - "There's nothing in this, just potatoes and ham! You can have it!" Only after intense questioning do you find out that, oh, well, of course they added just A LITTLE flour. They do this for one of three reasons: a) protecting their recipe. That's fine, you can keep your recipe, but I'm not eating it if I don't know what's in it, b) they don't believe in gluten. Or food allergies. Or whatever. And they want to PROVE YOU WRONG. Offer them a laxative and tell them, "There's nothing in this but chocolate!" and see how they like it, or c) Again, they may be insulted that you won't eat their food. See above.
The food stealer - They can have any of the 1,000 items available before them, but they want YOUR food. You can approach this in one of two ways: a) plan to feed the masses and double your bring-food-everywhere burden (despite the fact that you may then endure insults about your food not tasting "right"), or b) repeat after me, "No." "NOOOOO." "No way, man, get your own!" Slap grabby hands if you have to.
Disclaimer: This is a silly post that is not meant to offend, demean, degrade, or contaminate you with gluten in any way. However, you may not want to eat the unwrapped chocolate I just offered you.
ALERT ALERT ALERT
Baby #4 will be joining the gluten free household this spring! YAY!
