Why?

In the "learn something new every day" category, apparently when they build manufactured homes, they put the linoleum down first, then build the walls.  This is the linoleum coming out from under the walls around the bathroom.  And stopping 12" into the dining room.  WTH?

The entry way had carpet everywhere except that little rectangle.  How it stayed flat under the carpet is a mystery. As soon as we pulled up the carpet, those edges started curling up.

And you put linoleum in only half the bathroom?? Why??

The lino from the bathroom even crept into the one bathroom.

And plastic came out into another bedroom. Where the heck is that coming from?
