I’m all ears.

I told the broker I am LOOKING FOR AN INVESTMENT WHERE I CAN GET A DECENT ROI, but the broker's ears are deaf to what I want and he still proceeds to PUSH ONLY WHAT HE HAS to fill his wallet with some easy cash when you are dumb enough to go look at those three houses.

Use the computer between your ears. 

If it's a legal issue then I'm all ears but it often comes across as a moral objection and it's over a technicality.

Tell me why the toilet leaked into the basement for hours because this dumb dude didnt set the wax ring correctly.

An LOI can have an informal ring to it, it is not a contract, its just a statement of purpose to move forward in negotiating a purchase, with a tentative offer price.

Joe likes Livonia, Redford PlymouthDeals are all over the inner ring burbs of Detroit. 

He looks into your eyes and ears, and up your nose with a little flashlight.

If someone here has a scenario where it's appropriate to do otherwise, I'm all ears.

And wearing a fake wedding ring only works if you're good at lying and don't have any subs that you used before and who know differently.
