"You always know what's best for your family..." so you prevent your husband from making a total fool of himself by going out in suit his grandfather used to wear to the track back in the 40s (why does he even OWN that thing?)  Good for you.

But "you always know what's best for your family..." so you serve them cheap, fatty, deep-fried and frozen chicken parts instead of actual, real food?  I'm not buying it, lady.   I think it's more like "you know what's best for you- spending less time in the kitchen and more doing stuff you like."  I totally understand and endorse your philosophy.
