Here are some possible interpretations of "sticky" when used to describe a character:
* Clingy or possessive: A sticky person might be overly attached to others, demanding constant attention, and struggling to let go of relationships.
* Persistent or determined: Like sap that's hard to remove, a sticky character might be relentless in pursuing their goals or holding onto their beliefs.
* Unpleasant or difficult to deal with: The sticky quality of sap can be unpleasant to touch, and in the same way, a "sticky" character might be annoying, difficult to reason with, or even manipulative.
* Slow or methodical: Sap flows slowly, so "sticky" could also suggest a character who moves at a slower pace, thinks carefully, or is deliberate in their actions.
Ultimately, the meaning of "sticky" depends on the context of the story and the author's intent.
To understand the meaning in a specific instance, you need to look at how the character acts and interacts with others, and consider the overall tone of the writing.
