In life , things can get tough . Sometimes , it is good not to let things bother us . Letting things roll off our backs is a good life skill . When things roll off our backs , they are out of our minds . They no longer bother us . But , let's face it … sometimes , things do bother us . Sometimes in life , we are pushed to our limit . So , on today's program , we talk about those times when we have had enough ! We have a couple of expressions that help us describe that state of mind . They involve the word straw . First , let's define straw . Straw is the dry stem of plants like wheat or other grains . TheHayManager.com says , “Straw is yellow or golden colored and is a byproduct of the grain harvest .” In other words , it is a waste product of wheat . But it has many uses . In a garden , you can use straw on top of soil to keep it from drying out . Straw can also keep weeds from growing . Straw , especially dry straw , is not very nutritious . But because it is hollow , straw makes excellent bedding for animals . Horses , cows , goats , and camels may enjoy a good night's sleep on a straw bed . Animals not only sleep on straw . Some may also have to carry bales of straw on their backs . And that brings us to this expression : the straw that broke the camel's back . The straw that broke the camel's back was one straw too many . With that piece added to the camel's back , the load became too heavy to bear . In other words , it is the last thing to happen that makes you give up on something . Here is an example : Let's say I have a friend who constantly lets me down . When he says he is going to do something , he never does it . And he always promises next time will be different . Well , one day I told him I was going out of town for two days and needed someone to feed my cat . He offered to help . I was not so sure . But he promised that he would take care of my cat Meepers . I believed him and left my cat in his care . Well , guess what ? He forgot to feed her ! She went two whole days without food ! Luckily , Meepers is a very fat cat . But still , that was unforgivable . It was the straw that broke the camel's back . I am never trusting him again . We have a similar straw expression but without the camel . The last straw is the last thing that pushes you to some sort of limit . You cannot take a situation anymore because of that last straw . Here's another example : Earlier this year , I joined a local yoga studio . It was very close to my home . So , that was good . But other things about the studio were not . It was very small . So , when I did yoga positions , I would often get hit by other people . That bothered me . Also , the teacher talked too much about modern philosophy during the class . That got on my nerves . But then she raised the cost of her classes . The price almost doubled ! That was the last straw . I decided just to do yoga at home with a YouTube instructor . I save money . And if the instructor talks too much , I can just turn down the sound . Don't forget to practice using last straw or the straw that broke the camel's back .
