Maybe the ears are looking / listening.
This morning, on Facebook, and I see an ad for a very specific Yogurt my wife asked me yesterday (standing in our kitchen) to get at the grocery store. This ad / Facebook is on my iPad, Facebook is not even on my phone, the iPad was sitting 20' away. NO way it was a coincidence, it was a specific brand and neither of us had viewed it through our wifi router either. If you don't think 'big brothers' are watching, and listening, watch a great documentary on Netflix called The Social Dilemma.
