Silly of me - I should have learned my lesson long ago.

Silly of women to try and be young all the while.

It would be silly of me to argue something I don't understand.

It had been silly of her not to share everything with him.

It seems silly of me not to know your name.

It was silly of her to be nervous in the first place.

It was silly of me to come down here at all.

How silly of her, but she was happy for them.

Silly of the Americans to be troubled over a few words, he thought.
