The speaker is remembering someone close, a person who held their hand, visited, gave gifts for no reason, and shared plenty of hugs and kisses. The opening questions sound like the speaker is asking that person directly, but the plain "I do" shows the real point: the speaker remembers everything, even if no one is left to answer.
Then the poem turns. "You were here yesterday, but gone today" is blunt, and it suggests a sudden loss. The poem never says whether the person has died or simply left, so that part is open to the reader. The speaker looks ahead to days, months, and years without them. The closing image of a winding road to "memory lane" turns remembering into a journey, a way to keep visiting. The mood is quiet, tender, and sad, but "See you then" ends on a small, hopeful note.
