Michael was really tired after a long day at school. He helped his mom with cooking and cleaning the kitchen.

But for his tiredness after a long day at school, Michael would have helped his mom with cooking and cleaning the kitchen.

Had Michael not helped his mom with cooking and cleaning the kitchen, he wouldn’t have been really tired after a long day at school.

Not until Michael had helped his mom with cooking and cleaning the kitchen did he feelreallytiredafteralongdayatschool.

Tired though Michael was after a long day at school, he helped his mom with cooking and cleaning the kitchen.
