The urge to grab Stanley and just shake him until he somehow miraculously understands grows stronger by the second. No amount of talking seems to make his brother understand the dangers and consequences of using the portal. Sure, Stanley might not have gotten a PhD in physics and he won't understand all the complicated theories behind interdimensional travel, but Fords knows his brother isn't stupid.

He's just being stubborn. And that's the most frustrating thing about this situation.

"I'm talking about our home dimension, Stanley. It would destroy ours and then we won't have a home to return to."

He's too tired for another fight, his patience worn thin after a very, very long day. Trying to explain anything when Stanley is being stubborn is about as effective as talking to a wall (although the wall would be a lot less infuriating), but still Ford tries one more time to appeal to him.

"Will you please just listen to me? For once? I was stuck between dimensions for thirty years, I know what I'm talking about. Do you really want to risk that? Make it so that we— the kids—don't have a home to return to?"

His voice is subdued, but it's the kind of strained subdued that implies he's already at the end of his rope and he might as well be yelling.
