Or, hell, maybe both. Exhibit A:
Yep, that's my iPhone charging cord that's been chewed into two pieces. Note the multiple sets of teethmarks. It's as if the culprit tried out different spots before settling on the perfect place to ruin my cord.
Why, yes, those are scratch marks on the surface of my table. The cord wasn't on this table, FYI. The marks are from Christmas 2009.
Of course I'm in charge in my house. Why do you ask?
