When parties you know are coming up make foods safe for yourself & when you find a yummy dessert make it for all to enjoy... Works wonders!
Also have a safe bag of goodies in your desk, in your car, & a bar in your ourse at all times... I know many of my friends love to snack on chocolate, I'm not a big choc. fan so I take pretzels or another snack I enjoy...always ends up they eat my pretzels too... But I do't let them stick their gluten hands in the bag!!!!!!
Keep up the good work on your new gluten-free journey...
