Here's why:
* Personification is a literary device where human qualities or abilities are attributed to inanimate objects or abstract concepts.
* In this line, the speaker is describing an object (likely a flower or something similar) as being "pink with speckles." This is a simple, descriptive detail.
* However, the second part of the line, "I have looked at it so long I think a part my heart," is where the personification kicks in. The speaker is assigning a human emotion (thinking) to the object. They are suggesting that the object has captured their attention so deeply that it feels like a part of them.
This use of personification creates a sense of deep connection between the speaker and the object, making it seem more than just a physical thing. It evokes a feeling of awe, wonder, and perhaps even love.
