When doing laundry you hear the normal sounds.
The washer sloshing.
The dryer humming.
Not in my house.
When my washer finishes spinning I hear things rolling around.
As my dryer does it's thing I often hear what sounds like rocks
So I go to inspect.
After doing a load of my daughter's clothes
I find this type of thing waiting for me.
Sometimes I never know what will come out of the wash.
