The natural world gives us many of our expressions -- from weather to animals to plant life . Today we talk about a kind of flower . We often say we are fresh as a daisy after resting or getting cleaned up . Here is an example . After an all-day hike , I was very tired . But after a shower and short rest , I felt fresh as a daisy and ready for the next activity . Looking fresh as a daisy can also describe a place or room that is clean and orderly . For example , after the man cleaned and painted his kitchen , it looked fresh as a daisy . When a child is learning to walk , they often fall . To encourage them to stand up and try again , we might say “upsy-daisy !” We also might say “upsy-daisy ” when we lift a child up . It just sounds cute ! Speaking of children , a popular activity with some is to connect flowers together , like a chain , and wear them . Because of their strong stems , daisies are commonly used to make “daisy chains .” A daisy chain can mean any connected events , experiences , happenings , or things . A daisy chain is also used to describe electrical signals that are connected in a system . Sometimes , this can be used as a verb . When the Internet went down , I had to daisy-chain my phone to a friend's computer to share some videos . There is also a strange way we use the flower “daisy .” If someone is “pushing up daisies ,” they are , unfortunately , dead and buried . This comes from the fact that wildflowers often grow on top of graves . We may use daisies for this expression because they grow easily and wildly in nature . It is important to know that we only use this expression informally . Sometimes we use it as a joke .
