"Things may start to move fast - we'd better decide what to do next."

But he'd better decide to let this thing be arbitrated.

"You better decide what to do pretty soon, or there could be a big mess in the car."

But you had better decide quickly; before the passing of another day I will need to eat.

"And you'd better decide right now if you want to 'win' or not!"

Now you'd better decide what you're going to do about it.

I'd better decide on the things I want and get them away.

But you'd better decide if you want to trust me or not.

You'd better decide what you're going to do about it.

They're going to be here soon, and we'd better decide right now what to do.
