Anger has a way of seeping into every other emotion and planting itself in there.

The line frames anger not as a single, isolated feeling but as a contaminant that migrates into other emotional states—grief, fear, love, even joy—until it subtly reshapes how a person experiences them. “Seeping” suggests something gradual and hard to notice, while “planting itself” implies anger can take root and grow, becoming a default lens through which events are interpreted. The observation functions as a warning: unresolved anger tends to generalize, turning unrelated situations into occasions for irritation or suspicion. It also hints at emotional self-awareness as a remedy—recognizing anger early, before it embeds itself in the rest of one’s inner life.
