Unsafe Around Sharp Objects

I just got back from the drug store with a stash of vitamins and magic herbs that will improve my memory, help me sleep, and make My Lady Wonder Wench putty in my arms. And you know those plastic wrappings they put around bottle tops to keep the bad guys from dropping their stuff in there while nobody's looking? I grabbed a knife from the drawer, and started cutting around the edge so I could open the lid, and My Lady Wonder Wench said, "Don't cut yourself." She doesn't trust me with sharp objects. What have I done to deserve that ? (For those of you who have been listening to this podcast for a while, never mind with your wise guy answers.)
