Lying in the grass beneath a tree, the speaker lets their mind drift back over the past. What comes up isn't one big memory but a loose pile of things: words that spilled out, hopes, and small moments that might otherwise be forgotten. The phrase "spilling over" suggests speech or feelings that couldn't be held in, perhaps said in a rush or without much planning.
The poem ends on a quiet question. The speaker wonders which of those words and hopes will "see fruition," meaning which will actually come true or grow into something. The tree and grass setting fits nicely with that idea, since fruit is what a tree produces after time and patience.
The mood is calm, reflective, and a little uncertain. Nothing is urgent here. The short, broken lines mimic the way thoughts wander when you're relaxed, and the speaker seems curious rather than anxious about what the future will bring.
