we all try to accomodate where we can by choosing meals to share that don't make them sick, they understand that we don't all have to eat that way (including their husbands and kids). They are grateful to have some sugar-free options, but they also understand that we find sugar free brownies and other sins against humanity to be disgusting. They are not offended by that (actually means more for them), and they simply volunteer to make certain items on their own to make sure that they have options. We all benefit from the flexibility.
