No MIL, my ravenous 3 year old (because you don't believe in snacking) can't just have a bit of my lunch. I'm very grateful that you've looked after him this morning, and then made a ham salad sandwich for us but the portion is far too small for either of us! I did offer to bring lunch with me, but no, instead you're huffing around the kitchen making another (weeny) sandwich for DS. He'll finish that then inevitably hoover up what's left of mine.
We're getting chips on the way home!
