a something to un-invent 

A Hearing Aid – 

A sound not worth hearing. They mumble. They speak too fast. They don’t even care if I can hear them. They are expensive. They don’t really work that well. There are a lot of things that I don’t consider doing because of my hearing problem. I think that is a good thing.

A Violation of Privacy –

A lack of freedom. Mark Twain got it right. The phone belongs in the closet. “Don’t call me, I’ll call you”. Better yet. Don’t let it ring and allow texting only. Going on vacation with a smart phone is really dumb. Just un-invent the ringer.
