My daughter and I must have looked tough that day.

I want you to understand these have been the toughest days of my life.

Just what we needed after a tough day of studying.

But she'd had a tough day at work, and it was really getting late.

Some believe the President is not building the authority he will need for the tough days ahead.

As it turned out, a tough next day for sure.

His was not your typical tough day at the office.

Just a tough day at the office for us today.

He looked like a grandfather who was having a tough day.

There were miles behind me; I'd got through a tough day.
