...the police radio. I thought it was the funniest thing when the officer kept emphasizing that you have to hold the button to talk and then you have to let go. And also, the key pad on the front, does not text--you have to actually communicate through speaking while pressing the button and then let go.
This presentation went on for probably 15 minutes and I kept laughing (quietly!) for most of that time because it was so funny hearing the officer explain how to push the button and let go. Really... has our generation forgotten how to use walkie-talkies/ radios now because of the convenience of a cell phone?
