Imagine utterances as little seeds of potential insight.

It takes time and effort to abduct these out of your experience into little packages that can be lobbed to others.

From your perspective they feel like sharing lovingly-crafted packets of potential.

But if the receiver isn't open to receiving them ("What do I have to learn from this person?" / "I don't have time for this right now") it might feel like getting pelted with pebbles.

Seeds can stay dormant for a long time, and withstand harsh conditions before ultimately blooming.
