After the mystery was solved, my girlfriend continued laughing about how seriously I had analyzed the object before asking her.
And honestly?
She deserved to.
I had somehow transformed a harmless scalp massager into a full detective case in my mind.
But the whole experience reminded me of something important:
Sometimes the simplest explanation really is the correct one.
And sometimes asking one slightly awkward question can save you from inventing an entire fictional conspiracy in your head.
