My FIL is very hard of hearing and refuses to get a hearing aid. Conversations with him go like this:
you (loudly): "How are you feeling?"
him: "What?"
you (even louder): "How are you feeling?"
him: "Why are you talking about bananas?"
He used to work for the company my wife works for now. Recently he called my wife to tell her about a great idea he had for the company and how she should send it in and make a million dollars. Although my wife tried to explain that there isn't an employee suggestion program anymore and the suggestion wouldn't work, he didn't hear her. This went on for a while and since she needed to go back to work she ended the conversation with "Ok dad, I'll send it to someone."
Once my wife tells you she will do something, she does it. So she researched who would handle that specific thing and sent the suggestion in, getting an email back that while worded better basically stated; "Why would you send us such an inane suggestion?".
However, my FIL is firmly convinced that he has had the most brilliant idea ever and that this is worth millions. And when we try to nicely explain that the company did not like the idea, he doesn't hear it.
So, how do I politely tell my FIL that he will not be a millionaire?
