Something we learned about our house - don't leave the attic door open

Most of our house is one story, but there is a bonus room over the garage which is Gary's hangout/media room/doghouse.  There is a small door in a hidden corner of the bonus room that leads to the attic.  Part of the attic floor has a plywood floor so we can use it to store seasonal things and boxes of stuff we don't know what to do with yet.  The rest of it is covered in deep blown-in insulation to keep the house below nicely protected.  This morning Gary was in the attic working on some wiring when our contractor arrived.  Wanting to speak with Tracy before he left, Gary hurried down, leaving both the attic and bonus doors open.  About fifteen minutes later we were standing around the kitchen island and a "snow" covered Macy appeared, looking more like a poodle than a yorkie.  She had obviously discovered a new fun place to explore and was covered in insulation puffs, very much like cotton candy.  I had to spend the next fifteen minutes combing her because a brush just caused more static, which made the insulation even harder to get out.  I think she learned her lesson - and so did we!
