Yes Ma'am decorates for everything.
She takes down the Halloween stuff the day after Halloween and puts up the Thanksgiving stuff. The day after Thanksgiving all that stuff comes down and the Christmas stuff goes up, and that stuff stays up until January 1st. Then there's general Winter decorations and added to that from time to time will be the Super Bowl, Valentine's Day, Ash Wednesday, then of course St. Patrick's Day, then generic Spring decorations go up with special stuff added for Easter, Mother's Day, Memorial Day, Flag Day, Father's Day, our Wedding Anniversary, then the generic Summer stuff goes up with special stuff added for Independence Day, and then comes Labor Day when generic Fall decorations go up, then we're back to Halloween.
My son that got married a year ago this October, told his mom that he's having a hard time living in an apartment where they don't have all the stuff collected yet to decorate like his mom does. It made her cry... and, buy a boat load of stuff to give him and his wife so they can start their own collection of stuff.
