A Bunch of Pretty Yellow Roses

Yellow means bright and cheerful so when my son's girlfriend was hospitalized last month because of Dengue fever, he brought her a bunch of pretty yellow roses.  Although a yellow rose is a symbol of friendship, the feeling of warmth and happiness it delivers will certainly put anyone in a bright mood.  I guess that's what made her recover from the illness faster.  Everyday that he visited her in the hospital, he brought a bunch of pretty yellow roses.  Sweet isn't it?
