Here's a weird, quirky thing in many episodes. Now Frank and Marie live across the street, so it only makes sense that they enter through raymond's front door. But frequently even when Marie is bringing a large pan of food, they enter and leave through the back door, which means they cross the street, go past the front door and alongside the house through the yard to get to the back door. It's only a few steps (once inside) to go from the front to the back door. So, it's completely illogical for the Barones to do this.

I know it's a convenient exit for purposes of filming the show, but it makes no sense at all...and yes, I know it's just a tv show.
