Which Calories don't Count?

We took the kids to McDonald's for lunch today because it is pouring rain and Justin and I are going to the movies by ourselves tonight. (Stop the presses!) So I didn't order anything so we could save money, and I thought I would just have a sandwich when we got home. But the pesky diabetes caught up to me and made me shaky so I just had to have some fries. And Caroline didn't finish her burger, so I ate the other half of that. But I have decided that those calories never count. Right? Calories only count if you are consciously eating. If you sit down to a meal that you prepare (or you order) for yourself. If you are eating someone else's food, they don't count. Those are their calories. Not mine. So, really all I had to eat today was a mini bagel and a glass of skim milk. I am a good dieter... I'll keep telling myself that when I eat Justin's popcorn tonight.
