(PUC-Rio - 2000)

¹On the way to the hardware store my husband and I noticed that our 15-year-old son's bike was parked outside the drugstore - unlocked and unattended. We were thoroughly annoyed because during the past year, two of his bikes had been stolen.

²In the name of tough love, we tossed the bike into the back of the truck and continued with our errands. 2 Several hours later we returned home. Our 17-year-old daughter met us at the door with a cat-that-swallowed-the-canary look. "Mom and Dad, the police were here while you were gone," she reported. "Someone called in your license-plate number for stealing a bike from the parking lot at the drugstore."
