Telephone Conversations: Obviously

We often overhear conversations that make no sense. More often, though, we overhear things that need no further explanation:

“Sometimes they’ll give it to you for free, which means that you don’t have to pay for it!”    

Is that so? Let me double check.

Free: adjective  

provided without, or not subject to, a charge or payment.

Oh, yep. I think you're right! DING DING, we have a winner!
