Where?

I run a pretty tight ship around here. ALL Stream children started doing their own laundry when they hit the double digits. Yes. 10 years old. Joy to the world for mom. I have been hearing about wool dryer balls FOREVER and finally bought some. I expect all 6 to be back in the little basket I have for them. All tucked in. Safe and sound. I bought 6. I have 4. 
Me "Where are the other 2 dryer balls? Who has them? They are in someone's laundry basket!! Everyone check!!" 
Tim "Is this how summer is going to go? You yelling about dryer balls everyday?"
Me "YES!! KEEP LOOKING!!"
