MALIBU — Calling it one of the biggest deceptions in family history, twenty-four-year-old Agatha Hilsbottom was stunned to find that the culprit for the six Starbucks coffee cups tossed behind the passenger seat of her car was her very own older brother. Hilsbottom discovered the empty cups one week after her brother completed his stay with her in California. “I knew they weren’t mine,” said Hilsbottom, adding that she always saves her cups for the next morning when she brews coffee at home. “I pretend I’m drinking Starbucks, but it’s really just my generic brand.” It was only after hours of reasoning that Hilsbottom discovered the only individuals who had been in her car in the past month were her brother and her Labrador retriever. “The dog seemed unlikely,” she said. Hilsbottom claims that the cups must have come from her brother, a man she says didn’t used to drink coffee from Starbucks. “I should have known something was off when he ordered a ‘grande’ at Coffee Bean.” We were unable to reach Agatha’s brother for comment at this time. Hilsbottom did confirm that she plans to clean the old cups from her car to use for pretend purposes.
