"Have one's hands full" means to be very busy or preoccupied with something. Here are some examples of how to use it in a sentence:
- "I can't help you right now, I have my hands full with this project."
- "Since the twins were born, she has her hands full all the time."
- "The manager had his hands full trying to resolve the customer complaints."
- "With the new puppy and her two young children, Sarah definitely has her hands full."
- "He won't be able to take on any extra work; he already has his hands full."
These examples demonstrate how the idiom is used to describe a situation where someone is overwhelmed with tasks or responsibilities. The tense of the verb "have" can be changed to reflect the time frame being discussed (e.g., "had," "will have," "has").
