People all around the world eat eggs . You can cook them in many different ways ! My favorite way to eat eggs is sunny side up . You heat up a pan , add some oil or butter and crack an egg into it . One side of the egg cooks until the white part becomes solid . The yellow part of the egg -- the yolk -- stays yellow . It looks like a happy sun on a plate . That is why we call it “sunny side up .” The adjective “sunny ” is also used to describe people . A very happy person can be described as sunny . We often pair “sunny ” with two other words : disposition and personality . Generally speaking , these are the ways that people behave . Let's listen to some examples using these common word pairs . My co-worker Pete is known for his sunny personality . Anyone who meets him likes him . He has a really sunny disposition and is always smiling . Pete always seems in a good mood . We can also call a very happy person a “ray of sunshine .” In nature , a ray of sunshine is the light from the sun . It cuts through clouds and darkness to brighten the day . People who are rays of sunshine do the same . They lift your spirits , or make you feel happy . They bring joy into the lives of others . But sometimes we use this expression in a sarcastic way . In other words , I might call someone “a ray of sunshine ” if they are acting unhappy or even angry . Let's say my friend is in a bad mood . There is nothing especially wrong , but nothing seems to make her happy . I could say to her : “Well , aren't you a ray of sunshine today .” Now , just so you know … this comment probably would make her even LESS happy ! Sarcasm can easily make people angry . So , if people are mad or sad for a good reason , it may not a good idea to say something sarcastic like this . Of course , no one is happy all the time . But some people are able to think about the good things in life more than the bad . In other words , they choose to look on the sunny side of life . On other programs , we have talked about this kind of person . People who see the good in nearly every situation are optimistic . They are hopeful . They see the glass as half full , not half empty . And that's all the time we have .
