I was OFFLINE

Have you ever known someone who was suspected of something and you never even seriously considered it until they started protesting their innocence loudly and repeatedly to the point of absurdity?

"It couldn't have been me. I was offline. I was cleaning my back porch. I went to bed early so I wasn't around. I have no idea what's going on. Fall cleaning has kept me so busy. What are you talking about? I have a busybusy life."

At that point you start to ask 'Is this the illustration of 'The lady doth protest too much' or am I getting paranoid"?
