I think it is order in because when you go out to eat you are "Eating out" but when a delivery man brings the food to your house you are "Eating In" I think....I always wondered that too.
We get "carry out" as I'm too cheap to pay for delivery.
Along the same lines, DH and I have the "curtain" debate all of the time. When you pull the curtain across the window, are you opening or closing them?
Thai please. I will have a seafood curry and shrimp coconut curry. Or maybe Pad Thai. No some Tom Kah. Oh boy some pineapple fried rice(my fav). Mi krop? Sure why not.
Lets eat.
