Two interesting points!
1) Until you mentioned it, it never occurred to me that she didn't mention a word about having lunch or feeding baby K.
It's true that we often feed babies on the go--a bottle here, a packet of food from the diaper bag there--so it might not seem worth mentioning. But did SHE not eat lunch? What, was a Starbuck's enough to give her energy for a workout and rejuvenate her from her unusually busy morning (hauling the kids into school, instead of simply having Kyron ready for the bus)?
That's makes two people who seem to have no mention of lunch in their day, as Dede didn't show up for lunch at her workplace, either.
2) She wouldn't have been able to unload the groceries until she got home around 1pm. It has been questioned before about whether she might have bought anything that needed refrigeration, and maybe that's what it is. But, actually, do we have any indication that she actually bought groceries? In her email, doesn't it say that she went to the FM stores solely in search of medicine for baby K?

At our Starbucks, you can get some sort of fruit smoothies. Even more importantly, you can have protein added to your drink.
A venti mocha chocolate chip frappucino with one or two packets of protein is very filling. Been there, done that. And, you can also get both breakfast and lunch sandwiches at many Starbucks. (Try the egg white and spinach wrap. Yummy. Hmmm..maybe I have time this a.m. for just that.)
