We had Lots of balloons at our house on Valentines Day ... but one day later the "regular balloons" were on the ground looking like they had been up all night at a party! The mylar balloons, on the other hand are still flying high above in the house. What's the deal?? I know that they will probably be up there until St. Patrick's Day when we will replace the pink, red and white with lovely shades of green!
