I was looking at the home of the winslows living room window, now if you would look at the living room window, it is very narrow (1) window that is-the narrow window next to the door, that is the only window in the living room that leads to the upstairs bedrooms- that window does not match the home in the opening credits that the winslows are singing in the living room with the piano-there are 3 large windows and a porch of the home of the winslows-did the winslows move to another home-:lol:

PS: where does the piano sits by the three windows that is in the opening credits- in the living room with the narrow 1 window not 3 windows and a porch?:eek: :lol:

As you already pointed it, it was a goof. They probably didn't bother with the details.
