So I say the sane thing to do is shut up.

But in view of the way things have turned out, it's the sanest thing we can do.

It is the only sane thing to do if you find yourself up there.

Not even if it is the only sane thing to do.

That is the sane thing to do and then leave each other alone.

The sane thing was to just get the hell out of Dodge.

They seemed the only sane things in all this madness.

If there was one, it would have been just this: in some situations, the only sane thing to do is change the rules.

They did not move or act like sane things.

I did the only sane thing that occurred to me.
