Thanks, but I still have troubles with that sentence, because I'm reading an article, the article is the next...
...Since I had never been there before and was unsure of protocol, I wore black dress shoes along with my black pants. I needn't have worried, as several people (men included) were in flip-flops or sandals....
So my question again is... the phrase <<I needn't have worried>> is ok?
and could somebody give me a fast explanation why can't I say...
<< I don't need to have worried>>>
or << I need not to have worried>>
Many thanks...
