She didn’t come to my party yesterday. I am sure she forgot my birthday.

Sam is late. Perhaps he missed the bus.

He didn’t buy the coat he liked. Maybe he didn’t have enough money to buy it.

I am sure Peter didn’t forget my birthday.

It is possible he has sold the car.

I am sure he has slaughtered his wife.

I am sure she didn’t steal the money.

I am sure he didn’t spend his last vacation at the seaside.

It was foolish of you to mention it to him.

I am sure he didn’t pay them. I'm not sure whether they have

torn the house down. It's possible he was fined for

speeding. They certainly met the deadline.

She didn’t come to school last week. Perhaps she was ill.

I can’t find my book. It’s possible I gave it to John.

I am sure she has left work early today.

It’s a pity she didn’t come. Maybe she didn’t want to come.

Perhaps the children were at school. It’s possible he heard what you said

about him. Perhaps the girls did not hear us.

Perhaps the girls did not hear us. Maybe you remembered his

address I am not sure whether Susan

passed the test.
