.....you discover while cleaning the house.
#10 You must be getting older because being down on your knees all day to vacuum under funiture makes you feel like Tonya Harding's boyfriend took a club to them.
#9 Judging from the number of cobwebs you sucked out of corners you shouldn't have seen so much as a fruitfly in the house all year. (You did have a fruitfly plague, though, in September due largely to those two forgotten tomatoes in a plastic bag in the utility room sink. Yeesh.)
#8 An upright, dusty drinking glass standing behind the couch. What the......?
#7 A stitch marker under same couch. Go check your project.
#6 Judging from the knickknacks the cats have knocked over you should seriously consider redecorating using anvils and bricks.
#5 Cat and dog hair....... so. much. fur.
#4 If you ever have the misfortune to get murdered, don't do it in a spinner's house. There will be no "A-ha" moment when they find 'a fiber!' that leads to the prime suspect in a few days. They will instead take years just to ID all the crap lifted from the crime scene.
#3 Eight cat toys under the furniture.
#2 Electronics are made of sterner stuff than you've been lead to believe since they've been functioning just fine swathed in a coccoon of dust.
And the Number One thing you'll discover while cleaning house........
Sunlight through the bottle of blue window cleaner makes pretty, wiggling
SPARKLIES-SPARKLIES-SPARLKIES on the floor for your cat.
