rough spot

That American Christianity is in a rough spot is no longer in dispute.

No woman minds that if she feels she is really helping her husband over a rough spot.

Indeed, I stumble as much as Old Trumpeter, our horse, going over a rough spot in the road.

The words came about me, binding up my doubts, making sound my heart, laying a soft touch upon every rough spot in my thoughts.

Sometimes there is a sudden upset as the toboggan strikes a rough spot on the hillside.

Then he waited for the rough spot in the street or the sudden stop at a light that would do the trick before he could stop it.
