Complete the weary traveler's diary entry by choosing the correct modal phrases for each blank.

"I sprinted all the way to the boarding gate, sweating and panting, only to look at the screen and find out the flight was delayed by three hours. I needn't have rushed! On the bright side, my lovely friend offered me a ride to the airport this morning. Because of her kindness, I didn't need to pay for a ridiculously expensive taxi."

"I sprinted all the way to the boarding gate, sweating and panting, only to look at the screen and find out the flight was delayed by three hours. I needn't have rushed!"

The traveler actually did rush (sweating and panting), but the delay meant the rushing was completely unnecessary. For actions that were performed but weren't needed, we use needn't have + past participle.

"Because of her kindness, I didn't need to pay for a ridiculously expensive taxi."

The traveler got a free ride, meaning the action of paying for a taxi was avoided entirely. When an action is unnecessary and therefore not done, we use didn't need to + base verb.
