When my Dodger was about 6 months old, we left to run a few errands....not thinking everything through (garbage up, doors closed and so forth). When we returned about an hour later, Dodger had taken one skein of yarn and ran around the house until it was unwound, then returned for another skein and proceded to do the same thing. Boy was that a chore to get unwound from the bushes and stairs...I swear she had it all planned going under, over and through every possible thing she could.
