I send my SO a care package every week and I will admit I have never sent a single stalk of broccoli or other healthy food. For that, he has a grocery store. Cookies, M&Ms, tea biscuits, cheese straws, chocolates, snack-cakes, fiddle faddle, poppycock and fake snow, yes. Carrots, no. One might assume that we are both dying of malnutrition, if one made the ridiculous assumption in the OP. The point of a care package is to treat someone.
And all the marmite/vegemite discussions these last few days are killing me people - killing me. Not a lot of marmite floating around in southern Wyoming these days.
