Charles Bukowski's poem "Bluebird" explores a speaker's connection with his emotions and his difficulty to admit that he cannot always be strong and intelligent. The poem starts with a refrain describing the presence of a "bluebird" in the speaker's "heart." It symbolizes his gentler and softer feelings. The song of the bluebird is often used as an image for love. It is also used to represent freedom because the bird can fly away if it wants to. So, the "bluebird in your heart" means that you are aware of someone's good qualities or affection for you. Sometimes we only see the bad sides of people but sometimes we can also see their positive traits which make them special even though we may not agree with some of their actions. It is very common for people to feel like they have a "bluebird in their heart", especially when they love someone. But sometimes when things go wrong or when we lose someone we love, this feeling can change and become painful instead. People use different words to describe this feeling, such as "missing", "grieving", "broken-hearted", etc. But whatever word you use, it means that you are aware of something being wrong but you cannot fix it so you try to ignore it by pretending it isn't there.
