When you give Grace a bead reamer, she'll need a bandage.
She'll trip on her way to get the bandage and knock over the permanent bond glue.
When she knocks over the glue, she'll bend down to pick it up and hit her head.
When she hits her head, she'll fall.
When she falls, she'll land in the glue.
When she lands in the glue, she'll stick to the floor.
When she sticks to the floor, she'll get angry and slam her hand down on her leg.
When she hits her leg, she'll forget she's holding the bead reamer until she sees the blood.
When she sees the blood, she'll remember she needs a bandage.
